PLEASE HELP! I know this is a bit long but I would appreciate anything I can get. I'm hoping someone with my identical symptoms can comment. I'm now 62 and have been having these "headaches" for 8 years now. For no apparent reason and almost exactly a week apart, I feel a dull sensation in the back of my head, lower left, in the neck area. (always left). Over the next few hours it is nothing more than a slight distraction, then, gradually, it usually turns into full blown pain on the left side of my head, mostly around the ear. It comes in waves and at its worst is a 15 on a 1-10 scale. The best way to describe the pain would be if you were pushing a screwdriver into my head through the back of my ear. During this time I can only sit up and wait for it to pass. I can "hear" crackling and all sorts of things going on in there. They usually last between 2 and 6 hours. I'm at the point now if I'm lucky enough to have a two hour one it's simply a nuisance. There's no way I can sleep during this as the pain is too intense. It is much worse when I'm lying down. Then, it's gone. Simply gone. Occasionally there is a "hangover" but mostly no after effects(unless it causes sleep loss). Nothing. Just gone. For seven (7) days I'm absolutely normal. Literally a week later it starts to happen again. I've had two MRIs and MRAs, (no tumors in there) have seen three neurologists, doctors, chiropractors, massage therapists, diet professionals. No particular thing seems to trigger it. Tried medications(including a powerful muscle relaxer that just made me feel awful) NOTHING helps. (a hot shower at times will help) While it's going on, it's much worse if I lay down. Otherwise, I'm fit, active and work full time in a normal life with minimal stress. Normal blood pressure and blood work results. ANY comment or help would be appreciated. Thank you. David.
