Hi I hit my head 2 Sunday's ago on a wood plat form at work then right after on a piece of steel on the back of my head. Was hurting for a little while on and off and then all of a sudden yesterday it started bothering me really badly in school in the EXACT spot where I had hit it. A shooting pain feeling, feels like there is pressure sometimes and feels like it's more inside my head. Feels like there is a tiny bump not big and it does not hurt when I touch it or apply pressure to it. Don't know what to do? There is a feeling in my head I can't quite describe. I described it as best as I could. What should I do?
