You need to see a physical therapist.
And,,,
I know many who haven't tried it will defecate on the suggestion,,,, screw them......
Try acupuncture. It saved my wrists and hands after a few accidents and other traumatic events left me with tendon and ligament issues... which saved my archery and pistol shooting.
Also, increase the amount of Omega-6 fatty acids I'm your diet, these are natural anti-inflammatory agents. Decrease their opposing agent, Omega-6 fatty acids. More; sardines, mackerel, salmon, grass fed/grass finished beef,,,, NOT flax seed or flax seed oil. Less; grains and legumes.
To note, I am not a physician,,,, my medical background is in cardiology and cardiac technology. But, after some very serious health issues, some life threatening, I did some heavy research into diet and how food and the chemicals and compounds in food effects us and our health. Thing is,,, a better diet can't hurt, even if it doesn't "fix" the problem being focused on at the time.
Even with a good healthy diet, p.t. will be needed.
