Last night i hit my head in the shower behind my forehead on the top of my head i didnt loose consciousness or anything. now i have like a indent in the center if my forehead. should i be worried? ive been tired

No: Assuming it's just a slight indentation it probably is superficial and will resolve on its own. Unlikely that you suffered a concussion,symptoms of which include confusion, disorientation, loss of memory, headache, difficulty thinking. Although usually temporary some symptoms can persist.
