I hit the top of my head really hard at work last night on the bar and it really hurt but obviously I had to carry on working as it was really busy.  I took some tablets as I had a instant headache and I've still got the headache now and it still hurts and aches. Do you think I should just wait it out and hope it goes or go get it looked at? I don't want to waste doctors time as it 'a headache'
