I hit my head pretty hard on the sharp corner of a book case full force last sunday. When I fell, I was anticipating hitting the bed, and did not immediately try to catch myself, unfortunately, my head hit hard directly on the sharp corner of the bookcase, probably one of the hardest I have had. I did not black out, but my ear became numb, and my head/shoulders hurt terribly. Then, throughout the week, I have been so tired, sleeping a lot more than I ever normally would, along with a dull head headache. On Friday, when I walked out into the cold, the spot on my head immediately began to throb. I instinctively reach to touch it, and it was very tender to the touch. It eventually subsided, but I have remained since then for the last two day with a dull head ache, achey shouders/neck, and my ear on that side seems to hurt, almost like when you are beginning to get an ear infection. Its hard to tell if I am just getting sick, or should I go to the doctor because of the injury to the head?
