Andrea welcome to Neuro Talk, if I may pry for a second what did the doctor say in regards to a cause, i know we all want answers to these type of things, especially when we dont have answers. I do think a good place to find an answer may be a doctor who is familiar with your body. I say this because I have MS and my symptoms may not match the person next to me with MS and theirs may not be anything i experience either, to many factors involved to get a definite answer, but do not hesitate posting a question , where i am not sure, I did a search here and it seems to be talked about in many forums, perhaps another member here may have a better idea on a forum to post questions regarding low platelets, again welcome to NT
