I have been experiencing headaches since my car accident in Nov08. I have been through Chiropractic, Massage Physical Therapy, Pain Management and then PT again myofacial(sp) release. Nothing seems to help. I have been taking muscle relaxers, I thought they were helping but I still get horrible headaches about once a week for three to four days. They put me on Topamax, and that was working for two weeks then yesterday I get a headache again. Xrays were normal, MRI of neck show slipped disc and spinal cord slightly rotated. I got Facet shots, which made the neck pain go away but nothing will help the headaches. The headaches start as tension at the base of skull and work up to top of head and they feel deep. Most times it is so deep it feels like a worm tying to dig out of my head. Light nor sounds bother me when I do have the headaches sneezing, bending over, laughing, and coughing make it worse. I have been keeping a journal and the PM and GP doctors cant pinpoint anything. I havent seen anyone else other than PT, GP and Chiro. Any advice would be wonderful.
