Neuropathy: You have a neuropathy . The question is why. You should ask your physician to consider a neurology evaluation. You also need a full medical evaluation to see if you have other medical condition. Your back may well be involved and that has to be integrated into your evaluation

There are literally: hundreds of reasons as to why a person might have a neuropathy. A systematic evaluation should be done. Be aware, that nearly 1/3 patients will have a neuropathy where a cause cannot be determined.
