Hit the top of my head by jumping and hitting a metal vent, don't think i hit it that hard but it left me with a headache, also, not sure if this could be connected but the right side of my cheek was itchy and left a circular red spot on it, could've been mold or something that fell off and just reacted to it, I dont know, anyways this headache lasted for the entire day, and I still have the headache the next day, today. Wondering if it could've been something serious. Thank you.
