I Was Wondering What Could Possibly Be Going On With

I was wondering what could possibly be going on with me. I have a small mole on my stomach then tends to get really itchy sometimes. I also have a small bump on my hair line that I have had for a few years. It also itches sometimes. A lot of the time when I get a scratch on my leg I get a bruise around it. And I have been getting dizzy lately. I'm a 23 year old female.
