SecondChances, you could consider taking taurine as a supplement. I have been taking it at 1 g/day for some time. It is the only supplement that I take. This (courtesy of mrsD) provides some background Benefits of Taurine | Life Extension.

Recently I developed painful osteoarthritis in one shoulder. Based on the anti-inflammatory properties of taurine (Taurine and inflammatory diseases) I increased the dose to 3 g/day and it is working well.

I don't know if what you have described has an inflammatory component but it might help.

I doubt that it will interact with your prescription drugs but obviously check with your doctor about this first.
