Hi I have a history of concussions 5yr old inadvertently walked under a swing not knowing that the swing had bin repaired and back in working order. Struggled though school had another when I broke my neck in a trampoline accident . Joined the army suffered another concussion 1962. 2010 fist seizure not diagnosed until later. Late 2011 a fall on ice another concussion. Early 2012 another fall backwards onto concrete caused by a seizure diagnosed as seizure disorder and brain damaged. Fallowing each concussion starting with the trampoline incident I noticed a tremor increase until now I can t even print legibly. My Dr. Doesn t think the concussions have any real baring on my hand tremors sighting my age 72 . Your opinion please. Frustrated Ted
Only a neurologist who has examined you and seen your MRI could make this call.  There are many kinds of tremors with many causes but in the end they are all treated in the same manner generally speaking. So in most cases whether it is related to some distant part of your history or a current one doesn't matter.  You should try to figure out what is frustrating you about your situation and speak to him or her about it.  That seems like a good starting point
