How to treat herpes
Get an accurate diagnosis from your doctor.
Herpes blisters are small, red, and filled with a yellowish fluid. Small blisters can cluster together and grow into a larger blister.
To rule out other causes, have your doctor examine the blisters and, if necessary, take a viral culture. Herpes virus type 1 usually causes blisters around the mouth, and herpes virus type 2 usually causes genital outbreaks.
