I slipped on hardwood flooring g and hit the back of my head very hard. That was 8 hrs ago. The back of my head hurts a lot and the muscles down my neck and across my upper shoulders are aching too. Putting ice on it seems to help a bit. I have also taken ibuprofen. Is there anything else I can or should do? BTW, I did not lose consciousness. I do not feel ill. It s just the bad ache at the back of my head. At times, my sinuses seem swollen.Any suggestions?
