Hi Doctor, I have been hit my head with the shower head about 4 times at almost the same spot ( first three times occurred about a month ago and 2 weeks apart each times. I was ok and feeling normal. But this time, I was having headache before I was hit. So it s been a day and I still have dizziness , so I am confused if the headache s been continuous with the injury. I only feel very little pain on my head like a pressure or something on the site of injury. I have no trouble sleeping, but I noticed that my eyes are a bit red (it could also be the heat from weather). Is it something serious to be worried about? It was my fault that I didn t change that bad shower head.
