A few weeks ago I had influenza. I was throwing up for a day and had to stay home instead of going to work. I woke up the next morning to get water because I was very dehydrated and I became dizzy while walking to the bathroom. All of a sudden I fell, I don t remember what I hit but it was either the toilet, the doorknob or the tiled floor. I woke up a little later and had a screaming head ache and a huge bump on my head. I have had this bump for two weeks and a brise for one week. Though it has became smaller there is still a bump and pain when touching it. Should I be worried?
