Sorry if this is a repost but the first time I posted the thread never appeared.
About a year ago strange red streaks began appearing on my back, butt, and thighs. Since then I've been to two doctors that have not been able to explain these marks. More recently a strange lump has appeared and it has been migrating down one of these streaks. Please help me I'm getting scared.
I posted an image (don't worry its from my thigh not my butt :D)
Can somebody tell me what is going on?
