I hit my head after a night out 5 days ago, I was drinking alcohol but I do remember the night, but not hitting my head. I woke up with pain on the left side of my head, specifically above my temple. It hurt to eat on the left side of my mouth for the next 2 days. Yesterday, when I woke up I blew my nose and blood came out (although not a lot) and I have been feeling a bit sick, although I m not sure if this is due to worrying about it. A small lump did appear above my temple about 2 days after hitting my head, and my head is no longer painful to touch, but it doesn t feel odd and slightly heavy, although it isn t a headache. I have now had a bit of diarrhoea today and I m wondering if that is connected and whether I should be concerned. Thanks.
