have you had unprotected sex recently? Is there a chance of exposure?

Herpes sores are open lesions on your genitals. They are open and puss for the 1st couple days. And yes peroxide would cause that affect. Then they scab ub and heal. Then they are gone until your next outbreak.

Herpes can cause flu like symptoms. Or you could have the flu which caused your immune system to weaken which in turn offered the perfect opportunity for an outbreak.

There is really no sure way to know unless you go to your doctor and have a blood test and culture done. Set up an appointment and see what they say. That way you can be sure and not have to worry.
