I agree with the other member who discouraged the meds. It amazes me that our society thinks it's ok to prescribe meds without knowing what the problem is. It sounds like a nerve problem and meds can definitely make things worse.
I have chemical and food sensitivities, and these exposures affects many systems including the nervous system- even can do permanent damage over time. Have you looked into that possibility. Of course, mainstream doctors won't acknowledge it or do the appropriate tests for it. You would have to see a physician specializing in Environmental Medicine. It may not be the answer to your particular problem, but it is worth looking into. Studies are finding more and more links between food allergies/sensitivities / chemical sensitivities and several ailments and diseases. Here are a couple organizations you can find online:
The American Academy of Environmental Medicine
The Chemical Sensitivity Foundation

Hope this helps.
