I have shoulder bursitis from a subluxation. How long does it take to heal?

It may not heal. Bursitis may not heal on its own. If it persists more than two weeks have it treated. .
Depends. 40's male bemoans "bursitis" as result of "shoulder subluxation". Unusual. Subluxation expected to cause labral &/or tendon injury. These soft tissue injuries are oft radiolucent. MRI neeeded plus hands-on & sensitive palpation by physician knowledgeable about shoulder biomechanics; highly specialized area of knowledge. Look to Osteopaths & Physiatrists for the most astute differential diagnosis. .
