My 15 year old daughter had some discharge in her bra a couple of weeks ago following a PE lesson. It looked like a sore round the nipple area that pus was coming out of. It seened to heal but then a few days later there was a kind of yellowish discharge in her bra again. It’s been like this on and off for awhile now. Any ideas? Have a GP appointment booked for the middle of February 1st I could get with a female doctor
