You could have osteoarthritis which I've been dealing with for over 60 yrs. Some days I b urn in certain areas of my body, lots of stiffness and sore muscles and lots of stuff. There are MANY arthritic supplements one can work with: glucosamine, shark cartlidge, and so many things we can try. Doing nothing is not the answer or just stay with pain meds. So much out there to work with but give them time to take hold in the body. All this pain and burning can bring on neuropathy.
