Hi luduplo,
Welcome to the forum! It sounds like you had a drop sz. and it wouldn't suprise me if all of this happened because of your concussion. I had a concussion a few yrs. ago after a auto accident when a guy rear ended me and sent me flying. The concussion caused swelling a bad brusing of my brain which in turn caused me to have many sz. Another thing that messed me up causing sz. is my gp put me on neurontin for pain and this drug was found to cause sz. for peopls so if you are taking neurontin for anything this could be the problem also. My advice to you is to see a neurosurgeon and have him/her do some tests on you to make sure there's no brain damage from the concussion. Also take vitamin B12 1000 mcg. once a day and cut back on the caffeine and nutra sweet because this will cause sz. and more pain when it comes to the concussion. I wish you the best and May God Bless You!
