Ask a Neurologist. Get Answers to Your Neurology Questions.
I would suggest a couple things. First, you should have nerve conduction studies performed (i.e. NCV/EMG). These tests will tell you if you have any nerve damage and, if so, where it is and how long it has been present (roughly). This can help with diagnosing a peripheral neuropathy as well, if present. In the meantime, you should ask your doctor for a nerve stabilizing medication such as gabapentin or pregabalin to reduce the pain and paresthesias (numbness, tingling, etc).
I would do that. There are other medications that can be added for improved pain control. She probably has a favorite or two that you might also need to take. If the pain is severe, as you say, and progressive, you might also request a referral to a pain management clinic. This is usually a team of pain professionals working under the guidance of an anesthesiologist. They will take a multi-pronged approach to getting your pain under better control.
