Ive been getting really bad bruises around my knee. I have like 9 of them, for no reason. I dont bruise easily and lately I have been. And I still have severe pain in my stomach. Sharp pains that just come and go. Sometimes they make me cry. Ive been having them for a while. I checked to see if I was pregnant, and im not. So the pains cant be related to that. Im 18 and I dont have any medical insurance. Thats why I havent gone to the doctor. I just really need some advice on this. Could it be cancer? I am a smoker. I dont know what to do anymore. Ive tried everything to make the pain go away. But I find myself just trying to ignore it like it will go away by itself. But its not. Does this sound really bad? Can someone just talk to me?
