Symptoms: For 3 years I have had constant tingling in my left hand/arm, left foot/shin, and left cheek/temple. It has not gotten better or worse and is always there. The tingling started in my forefinger and middle finger in my left hand...spread to my arm after two weeks, then my leg within a week, and then my face within a few weeks. The symptoms occurred at the end of a one month trip overseas (mostly in major cities but ended in the Cook Islands at a five star resort). My strength and coordination is fine. There is some disorientation/vertigo when I close my eyes and some frequent fatigue, though life with a 2 and 1/2 year old contributes to the fatigue

Tests: A Harvard trained neurologist at Vanderbilt reviewed two MRIs and an Echo and came up with no diagnosis - he looked for any indication of a serious disease/issue (e.g. MS). All blood test for lyme (4 tests), infectious disease, HIV, others have come back negative. I have tried various alternative approaches Chiropractic care, Acupuncture, supplements, cleanses, but have seen no impact whatsoever on the constant stage of tingling. I have done some chelation of mercury as well.

I'd appreciate any questions/suggestions for what my symptoms might suggest...even if they turn out wrong. I"m 47, if that helps.
