Hey. A few days ago I developed a bump on the outside of my vagina near the anus. It was pink and painless but now it's pink but like an open sore. When I bathe and pass water while cleaning my private area it burns :( I also have another sore but it is like a water bladder that crusts after a while :/ I also had a burning sensation while I pee but that stopped a day ago when I took Amoxicillin...anyone experienced this or can give some kinda advise.
