My 10 year old granddaughter has had odd things happening for a couple of years. She seems to be sick often. She has had her hair turn green, eye lashes and eyebrows fall out. A couple of weeks ago she passed out and stayed out for approx 2 minutes and was disoriented when she came to. We took her to the ER, she had a negative CT scan and they couldn t find anything wrong. Her PCP was not concerned and did not want to test anything. Today she has passed out again in the same manner, she cried she couldn t see, was sweaty, passed out for just seconds. She also complained of her arms hurting, (the first time it happened she had leg cramps). What could be wrong? Could this be symptoms of some sort of poisoning? Thanks in advance for any help you might can give. Respectfully,Tommie Smith
