I had 2 car accidents within 4 days, one that I was rear ended and caused neck trauma and head pain and has been ongoing for 4 weeks. I have had severe bouts of anxiety and an episode tonight like no other, while driving I felt pounding head pain and when I got to the house had a unbelievable raise in head temp, I was shaking and feeling like I might pass out, I ruled out a TIA or stroke from the ability to calm my breathing and my temp went away, appreciate any comments on what you think it might be
