Every now and then i have a sort of tingling sensation on the right side of my head. I have had a ct scan of my brain but not my head. The brain scan came out fine. I had been having migraines for about 5 weeks and the doctor prescribed Topomax. Eventually they went away but I'm now left with this tingling sensation only on the right side of my head. Do you have an answer for me as to what this could be.
