I hit the top part of my head 4 weeks ago. I did not lose consc or bleed. There was some redness and swelling for about three days. After the swelling went away and I could feel up there, I felt a small dent in my head, the size of a dime. I have worked and walked and cleaned and garden, washed cars etc since that time. Dont feel dizzy or sick or any pain. But, there is a small dent. Could this just be damage to my scalp maybe? Seems to be less of a dent as the days go by.
