My fiancé has two blisters one on each side of his testicles. He keeps itching them and broke one open into a sore. He thought it might of been "jock itch" and used the spray to help, but the spray would last for so long, now with using powder isn't even working. They aren't tiny little blisters like you normally see as normal herpies. It's one big blisters, on both sides. We have no idea what it is. He thinks it's from his ex girlfriend, but I have no signs of anything. Any info or thought would be grateful
Worst case scenario, it could be an abscess that developed from two blisters that did not heal properly and became really infected. You need to take him to an urgent care or hospital. He may need antiobiotics.
