Suzie--I just have to ditto what everybody said--go to the dr. After my crash I had a concussion & bleeding in the brain. I was in ICU for 2 days and then told to stay at home from work for 1 week. I also was told not to do anything to raise my heart rate for 6 weeks. And--I never had a headache at all. But I, too, couldn't remember the crash or anything that happened for the next few hours. Please let your doctor check you out.
