Hi I have a small skin colored bump right next to my right knee that has a faded blue spot in the center. I ve had it for six months -a year and havent gotten checked out because I didn t know what it was and was scared to tell my parents ( I m 16). But I looked at it a few days ago and it seemed to have gotten bigger. But it hadnt hurt at all or done anything other then make my worry since id found it.The next day and for three days know my knee where the bump is hurts on and of. Any idea what this could be? Can it be cancerious? I m haveing my physical on the 27th but any idea on how to deal till then?
