Hi , thank you for the response . My mother has severe arthritis in her spine. She is allergic to most prescription pain killers. Her Dr . put her on Tramadol. and she is starting to itch, how bad I don t know. However she is allergicto morphine ,on on and on .My question is , Is there anything else left that she might be able to take? I feel like we are at the end here,can you help?
