About 4 months ago I started with a dull ache under the right rib cage. Had abdominal ultrasound, blood work, chest xrays which all came back normal. Since this pain I have now started with tingling in the head, head pain behind the right ear, pain along the spine and just recently I have noticed occasional weakness in my legs. I was hoping that some of these symptoms could be related to being on Cymbalta or Welbutrin, but now am concerned it could be something more. Can you tell me of neurological disorders these may be symptoms of.

I will be seeing an neurologist soon but wanted to get some basic information before going to him.

Thanks
