Hi, I'm 41, 10 stone and am almost totally blind due to glaucoma and cataracts which cannot be removed. I've just finished a course of treatment for Breast Cancer and haven't got the all-clear yet. I tripped over and banged my forehead about 4 days ago. I hit my head on a metal door handle right above my left eye. Since then I've had an increasing headache, and my head feels very heavy. I feel sick and have no energy. My head feels tight and it seems to weigh a ton and hurt when I stand up or bend down. The bang was quite hard, it made a loud crack when it occurred but I didn't lose consciousness - just went a bit dizzy. As I have pain in my neck too, is it anything I should be concerned about or will it just get less painful on it's own? It wakes me up at night and I'm quite frightened.
