Hey.
You are not a professional and neither am I (even if I was one it would be really hard to actually determine what it is.). I think that the best way to know is going to the doctor and casually mentiont it to him/her and see what happens. Just to be safe.
Good Luck! Try to calm down a bit and go see what happens!
