Hi, I hit my head yesterday evening on a grand father clock hangin on the wall. There was no blood and there is no bump. I did have a headache so I took an aleve. I was also dizzy and tired. Today my head is still sore, I do not have a headache, but I just feel like there is pressure (kind of like when you are getting into an airplane) and I did get lightheaded a couple of times, also the back of my neck is a little sore.
