Alright, I'll do that. Thank you!
I would definitely have a GP or internist examine you. If necessary, you can be referred to a dermatologist. I wouldn't panic.
I don't believe I've had a change in my diet, I don't believe I've played any kind of sport that would cause this (nothing out of the norm), and as for sexual activity, while possible, I doubt it. I had oral sex about a month ago, but that was all the farther it went. I also don't have any contact with this person, so that makes it even more difficult. If it is some sort of STI, I'm not sure which. Been looking and I don't see anything quite like what I have. :/ really aggravating.
I would look at any recent sexual activity or sports for possible clues. Also any change of diet.
