I'm 19 years old and lately I have been getting some headaches over the past week or so they aren't horrible, but I can feel them, the past few days they have been going away/not as bad... but this morning when I was washing my hair I noticed a strange bump on the top right back side of my head. I don't really hit my head so I don't think thats it... I can't remember if I've had that bump before, but its hard and feels like its just my skull. I was wondering if that could be something in association with the headaches. I know many of you will tell me to go to a doctor if I'm so worried but I don't have health insurance to do so... :(
