now 4 months after being rear ended, I am still experiencing near constant numbness and tingling in both feet and my left arm and hand, along with neck pain, particularly on the right side of my neck and right shoulder right under my neck. I had MRIs, CATscan & xrays after the accident that showed nothing. I was thrown forward and backward (was wearing seatbelt) and hit the back of my head on the seat headrest and briefly blacked out. A week after the accident, when I tried to go back to teaching, I couldn t look at a screen or read without feeling nauseous. Followed up with orthopedist and was told I had post-concussion symptoms, but hospital never told me I had a concussion, though I kept telling them my head hurt. I ve been seeing chiropractor for about 3 weeks. Constant pins and needles were relieved by chiropractor for a time, but then got worse, and then better, but still there. Just had brain MRI ordered by neurologist. No results yet, but wants to do a nerve conduction study too. I m not sure why. I am 47 year old woman in otherwise good health. On neurologist s advice, once concussion symptoms went away (6 weeks after accident), I went back to normal life, but I still can t sleep well because my legs and arms go to sleep and/or tingle all night, and cannot be comfortable in any position for long.
