I've been waking up with a terrible headache every morning for the past three weeks regardless of what I eat before I sleep and how I sleep. I've tried no pillows, one pillow, and up to five pillows to stay propped up during the night, in case it was blood running to my head and staying there. I tried staying on one side all night, trying not to bend my neck in weird ways but the headache in the morning is still the same. When I wake up my neck is a bit sore like I slept wrong, but I haven't, and I feel the throbbing pain in my eyes and from the top of the back of my head down to the middle of my neck. Painkillers hardly help. I have to slowly stretch my whole torso before the pain subsides about an hour later. And I have also noticed that I can't crack my neck any more.
This is really starting to bug me, I haven't woken up refreshed in a long time, and I can't get to the doctor for another week. Any suggestions as to what I can do?
