Hi. First of all, i want to say sorry for my bad english. I am 23 years old university student. Yesterday(20th Jan) morning, I accidently bumped my head at the bed frame. Since yesterday, I’m having headache, nausea, vomiting, my sight become blurry and there is a huge bump (bruise) on my forehead. It was as big as a golf ball. There is no blood on that area. All the symptoms that I had still continue until today. I’ve been to the clinic yesterday & the doctor provide me with painkiller & medicine for reduce swelling. My question is since I still having those symptoms, should I be worried about something else; like concussion or brain injury?
