I walked into a very low no entry sign side on it went straight into the slightly left side of my forehead which was quite deep and resulted in me having stitches I wasent unconscious but I was seeing stars as they say and had to contain myself for a few minutes as I thought I was going to pass out a few weeks passed and I started to experience some dull headaches and was seeing waviness at the side of my head this passed after a few weeks this happened just under a year ago since then my cholesterol has shot up and I have lots of lumps and tightness on my scalp I have just noticed that just above my scar I have a dent on my head which wasn t there before. What could this b and what should I do?
