I can relate to all as I have Trigeminal Nerve Pain which then caused Hypnic Headaches…Hypnic Headaches only occur when you are sleeping. I am doing the Botox thing and have had three rounds. It’s not totally effective. However, thru my own research I have found a good nerve pain treatment called the Scrambler Technique thru the Mayo Clinic.. Additionally I have found a small clinic in Clifton, N.J. that does the nerve pain treatment. Non -invasive and doesn’t hurt…and is 90% effective. Unfortunately, my head pain is doing me in. Just took 40mg of Prednisone and it’s barely working. And now read about the Central Sensitization. I will do more research about the concept and the doctor. I used to be a gym rat and worked out all the time. I’ve stopped working out because of the headaches and think there may be a direct link to not working out!!
