i am a 29 year old female, 5'3, 160lbs. 8 months ago (april 2011) i noticed a "bruise" on my right inner thigh. i had no idea where it came from from or when i had actually gotten it & didnt pay much attention to it at the time. ive noticed it randomly over the months & recently realized that it actually feels like scare tissue even though it looks like a bruise. it dosent hurt but it does itch occasionally. is this something to b worried about?
