My brother has it in his legs and his condition is severe causing him much pain and loss of sleep. He has seen 5 to 10 doctors and his relief has been minimal.
My arms started burning and hurting a couple of years back. Doctor gave me some type of steroid cream. It didn't seem to help. The good news -- the pains got better with time although still far from perfect. Now a few months back my index fingers on both hands are burning.
