<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 66 years old and have neuropathy in my feet and legs. I am not diabetic. A friend told me Mentaxx would help, but I am allergic to many medications particularly sulphur and am leary of trying new meds. Is my friend right? Is Mentaxx a natural drug?  <response>: Hi, I am Chat Doctor. By Mental, are you mentioning Butenafine ? Anyhow, I would suggest you to visit and Neurosurgeon and have a proper Clinical Examination. You may also need a Nerve Conduction Study to know the extent of Neuropathy If you need any clarification have doubts have additional questions have follow-up questions, then please do not hesitate in asking again. I will be happy to answer your questions.
