I am 26 year old (F) and have spondylitis, while running I fell on a slippery floor. I fell backwards and banged my head to floor. There was no bleeding, vomiting or nausea.Its been 20 days now and I still have heaviness and slight pain since then. I went thru CT scan it says "cerebellar foliae are prominent" otherwise report is ok... what does it mean?? Do I need to worry and consult the doctor again?
