Tackling this pain requires proper treatment and a full-body approach, and it can sometimes make matters worse trying to fix the pain yourself. Often, doing ad-hoc shoulder stretches and over-working the related muscles could be prolonging the pain rather than fixing it. Shoulder pain should be treated on a case by case basis and assessed by a professional so that the advised healing can relate exactly to your unique condition and body type.
Osteopaths are well-educated in all matters of shoulder pain and can help to ease this disrupting pain with hands-on treatment
and specific exercise techniques.
