I fell in my kitchen abou 3-4 wks ago and landed on back of head and was unconscious for I think A few mins. It took over 2 weeks for the bumps to go down. I have had a horrible headache every waking moment since that s coming from where the bumps were and my vision has really been affected. I never got checked out but if there was something major like bleeding to the brain, is that still even a concern after all this time?
