I got into a car accident on Friday evening. Right after getting rear ended I suffered an over powering, horrible headache. I didn't lose consciousness at all, but I was completely confused and lost on what to do for about 2 minutes. All I could do was hold my head. About 3 hours after the accident i got another headache that has lasted ever since. It feels more like a migraine but I am able to function. I have suffered from headaches for a while. They started to calm down about 6 months ago, until now. Does this sound normal? I just don't know what to do and I'm sick of being in pain.
