Hey, Fancylady. I am so sorry to hear about all of the pain and suffering that your son is going through. I don't remember hearing about a possible cause...an accident? Actually, all of his symptoms can be attributed to diseases and disorders (like Multiple Sclerosis), or can be from an accident, or, an inherited disorder. Perhaps you can get him to a University Hospital, or a State Hospital so that they can run some tests. I am one who does not have the income for all of the testing, and specialist docs...so that is where I go. Could you tell us more?
