Chronic headache is a neurological problem which is best treated by a neurologist with a special interest in headache - in chronic daily headache treatment issues cna be complex and in general, if you can get an appointmnt at a headache center, this would be a good idea.
If the diagnossi is a primary headache syndrome like chronic migraine or tension headache, there is no long term deleterious effects on the brain or other organs. Secondary headache are headaches caused by something else ie vascular, tumor etc and the prognosis depends on what is causing the headache.
Relief with hyperextension of the neck does not suggest anything very specific. It may reflect that there is a muskuloskeletal component to the headche ie muscle spasm/ ligament strain which the extension releives somehwat. Having a physical therapist specializing in the neck evaluate your neck and posture may help
Good luck
I have daily headaches also, and get relief from 1. chiropractors and 2. stretching of my neck. I have been told that these headaches could and are probably tension headaches. The fact that you get relief from someone pressing on the muscles probably indicates that you have tight muscles. I have found that physical therapy has helped me. The physical therapist has given me daily stretching exercises that help keep the muscles as relaxed as I can hope, and also has helped in strengthening the muscles. Something else you may want to consider is massage therapy. This too can help relax the muscles in your neck, shoulders, and back. I hope this helps.
I have headaches like you've described since an injury last year. The only relief I've has been by using traction in physical therapy. Home units are available if traction proves helpful.
Because of the abnormal sound your hearing and lordosis issues in your neck, I'm curious to know if you have had a previous injury, possibly whiplash?
Ask your doctor about physical therapy. If possible, make sure you find a PT specializing in headaches. I'm on my third, now in a spine program, and she is the first who has focused in on the extreme muscle tightness at the base of my skull.
Good luck!
Have you had a MRI? I too had daily headaches and was pushed off by one neurologist. Later, another found a chiari malformation on a MRI. Then a year later another doctor did a spinal tap and found I have idiopathic intracranial hypertension.
Don't ever let a doctor blow off your headaches! If that doctor doesn't listen, go to a different one.
Good luck. Mel
