Do you take any food supplements? There are quite a few for you to consider which will may help you. Don't forget that with your appetite down as a result of the medication you must ensure that you are getting the right amount of vitamins and minerals daily. Besides these ordinary vitamins and supplements, some sufferers are taking Magnesium and Alpha-lipoic Acid to help with the pain, and swear by it.
I can neither recommend or condemn any of these last two choices. What I will
praise is the flexibility of the human mind, the way that it can bend and not break in adversity; the strength of human vision to look outside of the everyday for solutions to everyday problems. Maybe the beneficial effects of taking these last two are placebo. But, hey, if it works don't knock it.
