I have been suffering from headaches which morph into migraines for the last 19 years, but only this year have learned what they actually were. After visiting neurologists, orthopedists, you name it, I happened to be on a cruise and was hit with one of these debilitating headaches. They begin in the left side of my neck or skull (although they can also be experienced on the right side for some people) and they escalate into the most unbearable pain in my whole head, followed by vomiting. I have tried migraine meds, heat, cold, chiropractic, pain meds, and physical therapy, and nothing stopped these headaches from occurring. Back to the cruise...I had no choice but to go to the ship's doctor, who immediately diagnosed (without imaging) cervicogenic migraine, based on my history and symptoms. Once I got back home, I found my way to a neurosurgeon who referred me to a pain clinic, where I was given epidural steroid injections. I came to learn that the headaches were caused by neck injury (either traumatic or degenerative, in my case) which was inflaming and pinching nerves in my cervical spine, starting the headache and accelerating into a full-blown migraine (something that I wouldn't wish on my worst enemy). These migraines don't respond to medication, and the only relief can be gotten from going to the E.R. for a pain injection. The epidural injections are designed to prevent the episodes from occurring. Has anyone else out there experienced these types of headaches??
