My mother is 78 years old has heart condition with pacemaker, in remission with multiple myloma and has 3 crushed vertibrae (which doctors state cannot do anything else about do to health). She uses the fentynal patch of 50mcg every 72 hrs and aspirin for pain in back however, she is having a lot of stiffness and soreness in her hand specifically the right one more than the left. Has been using aspercreme for the soreness and unable to use any other creams (ben gay, icy hot etc.) as they burn her skin it is sensitive. Is there something else we can do to help ease the soreness in them for her?
