In diagnosing the causes of hip pain, it’s important to understand hip anatomy. The hip is basically a ball-and-socket joint similar to the shoulder joint and the arms. The hip joint is impressive in that it serves two factors, it is a support structure and also very flexible. Because it is a strong support structure, it tends to get injured. Because it’s very flexible, it similarly can be susceptible to injuries.
Prolonged sitting and activities like running or cycling can lead to tight hip flexor muscles and a variety of skeletal imbalances. Think: if you only cycle for exercise, certain muscles in your legs will get stronger (in a lot of cases you overwork these muscles) yet your core and outer hip muscles might get weaker from lack of engagement. So what? Well, these muscle imbalances often lead to skeletal imbalances and injuries down the line. If you have particularly tight hip flexors, your body will start to create an anterior pull on the pelvis (anterior pelvic tilt). You can identify an anterior pelvic tilt if your belly protrudes slightly in the front while your butt sticks out in the back (what some people refer to as “duck butt”).
5. Feel free as a bird. Open up those hips with yoga’s pigeon pose! Start on all fours with hands below the shoulders and knees below the hips. Bring the right knee forward until it touches the right hand and place the leg flat on the ground across the body (the right foot is now on the left side of the body, parallel to the front of the mat). Drop left leg to the ground, and extend it back with toes turned under. Keep the hips level, inhale, and walk hands forward. Exhale, and fold the torso over, lowering elbows to the floor. Stay in this position for 5-10 breaths before coming back up to switch sides.
Premkumar et al present evidence that the traditional “red flags” for ominous causes of back pain can be quite misleading. The correlation between red flags and ominous diagnoses is poor, and prone to producing false negatives: that is, no red flags even when there is something more serious than unexplained pain going on. In a survey of almost 10,000 patients “the absence of red flag responses did not meaningfully decrease the likelihood of a red flag diagnosis.“ This is not even remotely a surprise to anyone who paid attention in back pain school, but it’s good to have some harder data on it.
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.
You could do these moves all together as a single workout, or, as Miranda suggests, split them in half and do the first part one day and the second part another—"but do the warm-up with each one," she says. Those first three moves are meant to not only "wake up" the muscles, but also get your brain ready for the movement patterns to come. For that reason, she says that doing the first three moves "would be a fantastic warm-up before any workout."
The treatment of hip pain depends on the precise cause of the pain. Treatments can include rest, non-weight-bearing, cold application, and anti-inflammatory medications. For local inflammation, sometimes injection of cortisone medication (steroids) is used to quiet the inflammation. If infection is present, antibiotics are used. Fractures can require treatment with surgical repairs, including pinning, plates and screws, and total joint replacement. For severe arthritis, total joint replacement is performed when possible.
The hip flexors are the group of muscles that allow you to lift your knees toward your chest and bend forward from the hips.  What is collectively referred to as the hip flexors is actually a group of muscles that includes the iliopsoas, the thigh muscles (rectus femoris, Sartorius and tensor fasciae latae), and the inner thigh muscles (adductor longus and brevis, pectineus and gracilis).
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.”
