Our scuba dive guide had me do a back roll entry in the water and I believe I injured my neck. I have had headaches for two years that won't go away. Been to numerous doctors, MRIs, Cat scans, headache pills, chiro, etc. can get any help. Any one else have anything like this happen? Any successful treatments? Running out of ideas and can't take having a headache 24 hours a day anymore. Thank you.
