About 3 hours ago I whacked the left side of my head against a wall accidentally. It was a shock and I got up straight away as a reflexive response and just tried to shake it off. I’ve not had any severe symptoms and my head isn’t hurting that bad, but I have a very light aching sensation especially when I lie down. I really hate health anxiety, but hitting your head can be a serious situation and don’t think my situation is bad enough to go to the doctor but I also feel awful whenever I neglect a situation.
