I'm really panicking right now. When I woke up this morning I felt fine but when I sat up I got a really bad throbbing pain in the back of my head. I took a couple of pain killers and the pain is now gone. I don't know why but it's really thrown me, I get headaches on the front of my head, around my eye, quite often but this was new and I guess I'm worried that headaches can sometimes cause nausea/vomiting and I now feel really spaced out. I'm sure this is due to my increased anxiety, rather than the headache, but I am worrying that the headache is causing the dizziness and spaced out feeling.
My neck muscles do feel really tense, and I started knitting again last night for the first time in a while and I know I do tend to hunch over and raise my shoulders when I knit so I don't know if maybe that has caused muscle tension causing the headache at the back of my head - does that sound plausible??
