An injury to a ligament is called a sprain, and an injury to muscle or tendon is called a strain. Sprains and strains may be caused by repetitive movements or a single stressful incident. Symptoms and signs include pain and swelling. Though treatment depends upon the extent and location of the injury, rest, ice, compression, and elevation are key elements of treatment.


2016 — More editing, more! Added some better information about pain being a poor indicator, and the role of myofascial trigger points. This article has become extremely busy in the last couple months — about 4,000 readers per day, as described here — so I am really polishing it and making sure that it’s the best possible answer to people’s fears about back pain.
Hip tendonitis is inflammation of any of the hip tendons, or thick cords that attach muscles to bone. Similar to strains, hip tendonitis is commonly caused by overuse. And, also like strains, tendonitis frequently affects the same population—athletes who participate in cycling, swimming, running, and other sports that repeatedly stress the hip. High intensity interval training (HIIT) workouts and other activities that involve a high volume of kicking, squatting, and jumping can also lead to tendon inflammation.
Lumbar strain (acute, chronic): A lumbar strain is a stretch injury to the ligaments, tendons, and/or muscles of the low back. The stretching incident results in microscopic tears of varying degrees in these tissues. Lumbar strain is considered one of the most common causes of low back pain. The injury can occur because of overuse, improper use, or trauma. Soft-tissue injury is commonly classified as "acute" if it has been present for days to weeks. If the strain lasts longer than three months, it is referred to as "chronic." Lumbar strain most often occurs in people in their 40s, but it can happen at any age. The condition is characterized by localized discomfort in the low back area with onset after an event that mechanically stressed the lumbar tissues. The severity of the injury ranges from mild to severe, depending on the degree of strain and resulting spasm of the muscles of the low back. The diagnosis of lumbar strain is based on the history of injury, the location of the pain, and exclusion of nervous system injury. Usually, X-ray testing is only helpful to exclude bone abnormalities.
Before recommending exercises, physical therapists evaluate their patients to develop a routine that’s appropriate for their specific condition. Pariser says the following exercises, done at home and at the gym, are generally safe for everyone. “If a patient has already received a total hip replacement, however, certain precautions should be taken,” he says.
Imagine not being able to climb stairs, bend over, or even walk Changes in hip joint muscle-tendon lengths with mode of locomotion. Riley, P.O., Franz, J., Dicharry, J., et al. Center for Applied Biomechanics, University of Virginia, Charlottesville, VA. Gait & Posture, 2010 Feb; 31 (2): 279-83.. All pretty essential if you ask us! But that’s what our bodies would be like without our hip flexor muscles. Never heard of ‘em? It’s about time we share why they’re so important, how your desk job might be making them weaker (ah!), and the best ways to stretch them out.
The National Institute of Neurological Disorders and Stroke (NINDS) is a component of the National Institutes of Health (NIH) and is the leading federal funder of research on disorders of the brain and nervous system. As a primary supporter of research on pain and pain mechanisms, NINDS is a member of the NIH Pain Consortium, which was established to promote collaboration among the many NIH Institutes and Centers with research programs and activities addressing pain. On an even broader scale, NIH participates in the Interagency Pain Research Coordinating Committee, a federal advisory committee that coordinates research across other U.S. Department of Health and Human Services agencies as well as the Departments of Defense and Veterans Affairs.
How to: Stand tall, feet slightly wider than shoulder-width apart, toes pointed out at 45-degree angles (a). Keep your back straight, knees over toes and your weight in the heels of your feet (b). Engage your glutes and thighs as you lower into a deep squat until thighs parallel to the ground (or as close as you can get them) (c). Powering through your heels, push up to return to starting position (d). Repeat.
Hip bursitis — an inflammation between your thighbone and nearby tendons — is commonly diagnosed when patients have pain on the outer side of the hip. However, several other conditions can cause similar pain, and require different treatments. "Doctors often assume that pain on the outer side of the hip is due to bursitis. But 90% of the time, it's not bursitis," says Dr. Lauren Elson, a physiatrist with Harvard-affiliated Massachusetts General Hospital.
How to do it: Loop a resistance band around your ankles and lie on your right side with your right arm extended on the floor, left hand in front of your body for support. Brace your abs in tight, bring your bottom leg slightly in front of your top leg (let the inside of your top foot rest on the ground), and lift your leg up to the ceiling, keeping your hips stacked. Maintain tension on the band at all times and pulse your bottom leg up and down quickly 20 times. Repeat on the other side.
Without changing the position of your knees, bend at your hips and lower your torso until it’s almost parallel to the floor (or as far as you can comfortably go without rounding your back). Pause, then lift your torso back to the starting position. Be sure to squeeze your glutes and push your hips forward to lift your torso back to the starting position. This ensures you’re engaging your hip muscles instead of relying on your lower back. Do 10 reps total.
For example, your quadriceps muscles are a group of four that are located at the front of the thigh; one of the group members, the rectus femoris flexes the hip, which brings your lower extremity (thigh, lower leg, and foot) forward, in front of you. On the other hand, your hamstring muscles are located at the back of the thigh. When they contract, they extend the lower extremity, bringing it behind you.
Low back pain that lasts at least one day and limits activity is a common complaint.[7] Globally, about 40% of people have LBP at some point in their lives,[7] with estimates as high as 80% of people in the developed world.[22] Approximately 9 to 12% of people (632 million) have LBP at any given point in time, and nearly one quarter (23.2%) report having it at some point over any one-month period.[7][8] Difficulty most often begins between 20 and 40 years of age.[1] Low back pain is more common among people aged 40–80 years, with the overall number of individuals affected expected to increase as the population ages.[7]
Physical activity can also help you feel better. “Along with boosting your overall health, exercise can improve your OA symptoms” like pain, stiffness, fatigue, and even depression, says Leigh F. Callahan, PhD, associate director of the University of North Carolina Thurston Arthritis Research Center. One study found that people with knee OA who worked out regularly lowered their pain by 12% compared to those who didn’t.
Emerging technologies such as X-rays gave physicians new diagnostic tools, revealing the intervertebral disc as a source for back pain in some cases. In 1938, orthopedic surgeon Joseph S. Barr reported on cases of disc-related sciatica improved or cured with back surgery.[100] As a result of this work, in the 1940s, the vertebral disc model of low back pain took over,[99] dominating the literature through the 1980s, aiding further by the rise of new imaging technologies such as CT and MRI.[100] The discussion subsided as research showed disc problems to be a relatively uncommon cause of the pain. Since then, physicians have come to realize that it is unlikely that a specific cause for low back pain can be identified in many cases and question the need to find one at all as most of the time symptoms resolve within 6 to 12 weeks regardless of treatment.[99]
Since the hip flexors are so easy to overuse and strain, it is important to stretch them before exercise or strenuous activity. Because of their connectedness to other muscle groups in the legs (like the quadriceps), it is important to stretch the muscle group as a whole, not individually. This ensures that the entire area is warmed up and ready for the strain of exercise or activity, not just one or two individual muscles.
While a sharp pain in the hip, groin, pelvis, or thigh is an obvious sign of a hip flexor injury, pain in the lower back and leg are easy to misdiagnose. After all, it’s natural to assume that radiating pain in the leg or lower back originate from these areas. Unfortunately, diagnosing the source of a patient’s pain is not always straightforward. In fact, it’s possible for patients to go years with a misdiagnosed injury.
The lower back where most back pain occurs includes the five vertebrae (referred to as L1-L5) in the lumbar region, which supports much of the weight of the upper body. The spaces between the vertebrae are maintained by round, rubbery pads called intervertebral discs that act like shock absorbers throughout the spinal column to cushion the bones as the body moves. Bands of tissue known as ligaments hold the vertebrae in place, and tendons attach the muscles to the spinal column. Thirty-one pairs of nerves are rooted to the spinal cord and they control body movements and transmit signals from the body to the brain.

First and foremost, stop slouching. One of the most common causes of low back pain is poor sitting posture. The strain on the back while sitting in a slouched position can cause excessive pressure on the joints, muscles, and discs, causing pain. Learn to sit with correct posture and maintain that posture at all times to help decrease or eliminate your low back pain. Also be sure your workspace is set up properly at home and at work.
Why is back pain still a huge problem? Maybe this: “It is extremely difficult to alter the potentially disabling belief among the lay public that low back pain has a structural mechanical cause. An important reason for this is that this belief continues to be regularly reinforced by the conditions of care of a range of ‘hands-on’ providers, for whom idiosyncratic variations of that view are fundamental to their professional existence.”

You’ve heard the saying: it’s all in the hips, but for many of us, our hips – or more precisely, our hip flexors – are tight, stiff and inflexible. If you’re an office worker you can probably thank sitting down at your desk 8 or more hours a day for your tight hip flexors. Habitual sitting causes your hip flexors to tighten and shorten – adjustable standing desks, anyone?
Really a great content. Let me tell you first about hip flexor it is the engine through which our body moves. They control balance, our ability to sit, stand, twist, reach, bend, walk and step. One of my patient also suffering from same problem but due to lack of money he was unable to afford a treatment. So i recommend him a program to unlock hip flexor.

Medications: A wide range of medications are used to treat acute and chronic low back pain. Some are available over the counter (OTC); others require a physician’s prescription. Certain drugs, even those available OTC, may be unsafe during pregnancy, may interact with other medications, cause side effects, or lead to serious adverse effects such as liver damage or gastrointestinal ulcers and bleeding. Consultation with a health care provider is advised before use. The following are the main types of medications used for low back pain: 

When you tell your doctor your hip hurts, the first thing she should do is confirm that your hip is actually the problem. Women might say they have hip pain, but what they may mean is that they have pain in the side of the upper thigh or upper buttock, or they may be experiencing lower back pain, says Stephanie E. Siegrist, MD, an orthopedic surgeon in Rochester, New York, and a spokeswoman for the American Academy of Orthopaedic Surgeons. Hip pain is often felt in the groin or on the outside of the hip directly over where the hip joint (a ball-and-socket joint) is located.

Located deep in the front of the hip and connecting the leg, pelvis, and abdomen, the hip flexors— surprise, surprise— flex the hip. But despite being some of the most powerful muscles in our bodies (with a clearly important role), it’s easy to neglect our poor hip flexors— often without even knowing it. It turns out just working at a desk all day (guilty!) can really weaken hip flexors since they tend to shorten up while in a seated position. This tightness disrupts good posture and is a common cause of lower back pain. Weakened hip flexors can also increase the risk of foot, ankle, and knee injuries (especially among runners) Hip muscle weakness and overuse injuries in recreational runners. Niemuth, P.E., Johnson, R.J., Myers, M.J., et al. Rocky Mountain University of Health Professions, Provo, VT. Clinical Journal of Sport Medicine, 2005 Jan; 15 (1): 14-21.. So be sure to get up, stand up every hour or so! And giving the hip flexors some extra attention is not just about injury prevention. Adding power to workouts, working toward greater flexibility, and getting speedier while running is also, as they say, all in the hips The effect of walking speed on muscle function and mechanical energetics.
