Maybe something is genetically wrong with me. When I was 33 I got my first bursitis (right shoulder). The chiropractor said the bursa are like gelatin ball-bearings in the shoulder, and when one pops, the surrounding muscles become inflamed. Now 10 years later, I have it in both shoulders, and pain when I walk, in my left arch and right ankle. Once my ring finger knuckle hurt for a year. The doc said the X-Ray showed no knuckle between the finger bones. Is this a case of disappearing joints? I've tried glucosamine chondroitin and shark cartilage but I can't see any noticeable improvements. Is there any way to resolve (aside from pain killers and drugs that have unknown or risky side affects)?
