I was rear ended while parked at a stop light, the force of the impact drove me into the vehicle in front of me. During the accident my seatbelt pretensioner failed to work at the same time my sun visor unexpectedly dropped down swung towards me and my head struck the edge of the visor which made a gash in my forehead down in between my eyes, there was blood visibly running down my nose at the scene of the accident. I went to the ER afterwards to seek medical attention. 3 days after the accident i suffered a seizure, i have no prior seizures before this incident. Since the accident i’ve continued to have headaches, signs of short term memory loss, and having trouble finding words sometimes.
