Soft tissue damage/muscle spasms etc, can have lasting effects just as much as bone or joint damage.

Drs usually tend to think more in terms of bone/joint problems and not so much at the soft tissue part of things.

A good massage therapist, or possibly even a chiro that does PT type modalities like ultra sound, IF stim, low level laser etc should be of help.

If you want a MD then probably an osteopath or physiatrist (a rehab/sports med type dr).
