I was riding a tube down a slide at a water park 3 days ago when my tube flipped over. I get my head, above my ear, very hard on the slide. It left a line on my scalp, but not an open wound. I had shakiness, dizziness, disorientation (mild) after the fall. I ve had an awful headache ever since, dizziness off and on, and nausea until today. The pressure in that part of my head is so bad today. Should I go to the dr tomorrow even though it s been so many day?
