question: My 17 year old daughter has small bump on each side of her groin at crease under skin they seem to come and go over the past year. Took her at first to nurse practitioner and she said it was abscess and prescribes antibiotic. This was about a year ago. They have came and went several times since. They never break through skin. She said when gone seems to leave a shadow though almost like bruise. What should I do.
