I was hit on the forehead by a hockey ball. i went straight to the hospital, and i had bruising for days, but i still have a small bump after 6 weeks.

The bump may not: Go away completely and that's not uncommon for a severe bruise. The lump is just a cosmetic issue and does not signify any internal structural damage on the brain. I won't worry unless there are concerning symptoms such as increasing headache, vomiting, passing out, weakness etc.Applying warm packs and takings nsaids may help it shrink. Take care!
