God I wish I could offer a magic bullet to help,but we all know what works for one,does not always work for everyone.Let me put it this way,I have researched about an exercise strategy that is still experimental,but it basically states that you can get your cholesterol,blood sugars,triglycerides down by doing 3 minutes per workout,4 times a week within 3 months.Their theory makes you get on a stationary bike and pedal like you have a T Rex after your behind for the full 3 minutes!The guy who did it,lowered his blood numbers by 25%.Frankly,I do not believe in 12 minutes a week,you can become fit!BUT,I do believe that focused,and intense blood saturation(or filling up) of all muscle groups for a short duration(when I first started 5 yrs ago,it was a 10 to 15 minutes a day)over a period of 3 months,and you will feel changes,I have no doubt!It made me able to improve slowly but surely.There is something about getting your muscles completely full of oxygenated blood,for a short period every morning,that brings pain levels down for a large part of the day,not gone,but significantly lower.When I start every morning,all my joints and muscles are not in the mood,me either to be honest!If you can't exercise per se,try to do something that will bring blood to specific areas gently and keep doing it regularly.I am sorry to say that Pain is inevitable,but within a half hour after,you will feel better for quite a large part of the remainder of the day.One thing,as you get tired getting through life's daily duties,the pain returns unfortunately,so you must listen to your body,to avoid overdoing it.This one strategy,has given me my first real relief since I first had symptoms beginning in the late 90s.Unfortunately,it takes effort,but I must say I am 53,and my muscles are cut,I look fit and I haven't done any weights since 2002!(I just use my body weight).I hope that it can help some of you to function with less pain too.Please let me know how it goes either way,I would be thrilled if it helps one person to lower their pain levels,and to feel better.I still have a few other strategies,one really big one that is not going to be shared,till I am sure it is sound.Good Luck!!
