I agree with Caroline..Please go see your PCP..Don't scratch and be careful when you wipe as you don't want to spread these..You will mostlikely need to go on an antibiotic and a cream to help with the discomfort..
DOn't have sex with anyone while having these spots..
Herpes usually begins with a small cluster of blisters. Some women get them on their genitals, sometimes upper legs or buttocks. It does sound like herpes. Are your genital glands swollen? Do you have any flu like symptoms? However, even though it sounds like herpes it could be something else. You do need to get it checked right away. If it is herpes the doctor can give you Valtrex which works very fast.
