I was assaulted on Sunday morning and repeatedly punched in the head, I've had no sickness, no headache etc. I was checked over by paramedics the next day and they said I was fine and showed no signs of anything internal and advised me to stay home saying a&e wouldn't do anything. I've woken up this morning with a slight headache nothing bad. I have health anxiety and it's playing with my head. I've taken paracetamol to see if it eases but I'm scared. Any advice?
