there are so many possibilities that it would not be in your best interest for me or any medical provider to blindly guess. a description is not sufficient to make this important call. even dermaologists often cannot determine the true nature of a skin lesion just by looking at it. sometimes it need to be removed (biopsy) to have a pathologist examine it under a powerful microscope. whether than worry that this might be a skin cancer of some sort i would highly recommend that you see a dermatologist. you have worried about this weird skin lesion for two years so it is time that you take it this one more important step and allow a professional to address your concern.
weird bump on skin that changed from pink to brown and developed a sore it is firm and not painful. what could it be? . this bump developed a few years ago. it doesn't hurt but sometimes the skin around it gets very sensitive and feels like it's burning. it doesn't hurt but it has changed color and it developed a wound when i don't remember injuring myself there. it kind of worries me. any idea?
