My husband has had burning and numbness/tingling in his right arm, upper thigh and ankle for a year. It's starting to wake him up in the night so he's going to see a doctor (long overdue). There is no history of diabetes or MS in his family. He has sprained his ankle badly a few times and suffered from torticollis in his neck in the past few years. Any idea what this could be? Thank you for any feedback.
