There is controversy and scientific uncertainty about trigger points. It’s undeniable that mammals suffer from sensitive spots in our soft tissues … but their nature remains unclear, and the “tiny cramp” theory could be wrong. The tiny cramp theory is formally known as the “expanded integrated hypothesis,” and it has been prominently criticized by Quintner et al (and not many others). However, it’s the mostly widely accepted explanation for now. BACK TO TEXT 

At the very least, the tension and/or spasm in muscles that cross over the hip and attach onto the pelvis can contribute to imbalance, in terms of how strong and flexible each muscle group is in relation to the others. But muscle imbalance in the hips and the spine may make for pain, limitation and/or posture problems. It can also increase the healing challenge put to you by an existing injury or condition, for example, scoliosis.
Back “spasms” are a largely a myth — there’s no such thing a sustained painful contractions of muscles in otherwise healthy people (see Cramps, Spasms, Tremors & Twitches) — but the kernel of truth in the idea of “spasms” may be the idea of trigger points, which are hypothetical “micro cramps,” tiny patches of painfully contracting muscle. Although this idea is controversial, it is nevertheless one of the most likely explanations for common aches and pains that mostly stick to one area (especially the back) and have no other obvious cause.

MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.

They are “fine print,” but more meaningful than most of the comments that most Internet pages waste pixels on.
The lumbar (or lower back) region is made up of five vertebrae (L1–L5), sometimes including the sacrum. In between these vertebrae are fibrocartilaginous discs, which act as cushions, preventing the vertebrae from rubbing together while at the same time protecting the spinal cord. Nerves come from and go to the spinal cord through specific openings between the vertebrae, providing the skin with sensations and messages to muscles. Stability of the spine is provided by the ligaments and muscles of the back and abdomen. Small joints called facet joints limit and direct the motion of the spine.[30]
Stop listening to other people’s horror stories. You know the scenario: You are bent over in obvious pain, waiting to see the doctor, and the person next to you tells you a 10-minute tale of how their Uncle Gordon had low back pain that required injections and surgery. But the pain still didn’t go away. Stop listening to these terrible stories. Most low back pain is short-lived and can be managed quite effectively with exercise and postural correction. Of course, some low back conditions are serious and require surgery, but that is a conversation you should have with your doctor, not the guy in the waiting room.
How to: Lie on your back with your right knee bent and foot flat on the floor (a). With your left leg fully extended, press into your right foot to shift onto your left hip. This is your starting position (b). Then, squeeze your right glutes to press your left hip open until you feel a stretch, pause, then return to start. That’s one rep (c). Perform six to eight reps, then repeat on the opposite side.

In both younger and older patients, vertebral fractures take weeks to heal with rest and pain relievers. Compression fractures of vertebrae associated with osteoporosis can also be treated with a procedure called vertebroplasty or kyphoplasty, which can help to reduce pain. In this procedure, a balloon is inflated in the compressed vertebra, often returning some of its lost height. Subsequently, a "cement" (methymethacrylate) is injected into the balloon and remains to retain the structure and height of the body of the vertebra. Pain is relieved as the height of the collapsed vertebra is restored.
