Hi, Here s the thing, took a bad fall in jujitsu, hard throw and slammed my head into the ground. I wasn t overly concerned, i had incidents in the past where I ve hit my head and lost my vision for 5 - 10 minutes. I was nauseos and confused but it appeared to go away so i didn t bother trying to get an appointment with NHS. Since then I ve noticed a marked decrease in appetite and severe headaches and now I m a bit concerned, it s been two weeks since the fall, I ve abstained from sports but today I began getting these odd sporadic stabs of pain in one specific area on the right side of my head, now i m thinking I should have gone in for an MRI. Please advise.
