Soft tissue rheumatism syndrome?

First of all I wasn’t sure where to put this story, since I am not sure in which group it belongs.
Since the early nineties I have had trouble with what I thought were my joints but now I think it have been the tissues around it. My wrist started to get pain full first. Physiotherapy and injections didn’t help. I was diagnosed with DeQuervain tendinitis. Since I worked in healthcare at the time my wrist kept bothering me and after many times complaining to my doctor, I finally had surgery. About two years later my shoulder started hurting and it felt like it was on fire. I had several visits to an orthopedic specialist and he told me it was a rotator cuff tendinitis. I had surgery and they removed a little piece from my clavicle. Over the years I had carpal tunnel, tennis elbow, ischial bursitis, a cyst at the back of my knee and bursitis on the inside of my other knee. Many of these painful episodes come and go. But I suspect that in the beginning it was caused by repetitive movements. Now I don’t have to do much repetitive movements to get the tissues irritated. I go to the gym but have to be careful what I do, because I don’t want to irritate anything. I know many people get the same complaints like tennis elbows etc. I just seem to get it a lot faster then the regular person. But I wonder what I could do to avoid these pains? There is a huge shortage of doctors where I live, and for orthopedic appointments you have to wait almost two years. The doctors for rheumatism don’t accept any new patients at this moment. I don’t have much help from that side. So I hope there might be people here with the same challenges and we can give each other advice?
