In the last 18 months I've had several episodes with varying neurological systems. In early 2008 my only symptoms were dizziness (not vertigo -no spinning), especially when driving, and tinnitus in both ears -- this lasted about 2 weeks. I had a repeat episode, also for about 2 weeks, in July 2008. Then in October 2008, I had an episode that included the dizziness and tinnitus but added tingling of the back and top of the scalp to the mix. My primary care doctor believed I was suffering from a sinus problem, recommended I quit smoking, and prescribed Chantrix. A week later I visited an emergency room after I felt something like electricity pass through the right side of my body, followed by twitching in my face. The ER doctor believed this was a reaction to Chatrix. By February 2009, my symptoms included dizziness, tinnitus, and tingling of the scalp and of the face (both sides, at different times). My PCP did blood work, which came back normal (thyroid, lyme test, blood sugar, etc), except that I had a slightly elevated white blood cell count (10,800). I also had an MRI without contrast, which came back normal. My doctor said this could all be a reaction to stress. I work full time and have two small children, so I guess I have at least as much stress as anyone else. I had no symptoms between Feb and June, but about three weeks ago all of my symptoms were back, with the addition of numbness of my arms and legs (both sides, at different times). I will see an ENT next week and a neurologist in 2 weeks, but in the mean time, I'm at my wit's end here. Not all of my symptoms are present together at the same time -- they come and go all day in various combinations, until the attack ends (so far, the longest attack has been 4 weeks). Could all of this be caused by stress, or is something else going on here?
