I to am so sorry for you and your Mom. Lots great info has already been given to, only thing I would add is the names of a few meds that you gals can research and ask informed questions about to a Dr. Cymbalta is good for pain and depression, Lyrica for the burning pain, Nortritylene for pain and depression ( can be taken with Cymbalta) and Tranadol for pain. Keeping warm is one thing that helps with my arms. Good Luck to you both.
