Hi Beth. Welcome here! Very nice of you to worry about your mom. PN is a very difficult disease to treat and it can take several trial and error tries until she finds out what helps her. I have tried Lyrica and it does give me some releif. I take up to 150 mg a day. Sometimes my pain is better, sometimes it is worse. I don't know what determines that, but i am happy for the good days. I have learned a lot here about nutrional support for healing nerves. Perhaps you could jump to "vitamins and supplements" and check some threads that have a great information about nutrients that can support your mom's healing.
