These are very suspicious for herpes simplex virus lesions. Herpes forms in clusters of blisters that hurt or burn especially when touched.
You should see a Dr for diagnosis, to do a viral culture (swab) of the lesions and bloodwork.
Most people (70%) acquire herpes from an asymptomatic partner, meaning their partner has no symptoms and does not know they have it. Herpes can also be passed through oral sex if the person has a cold sore.
Early treatment with prescription medication, Valtrex or Acyclovir , will shorten the duration of the lesions and stop the virus from replicating. This lessons the chance of recurrence and makes any recurrences less severe.
I am available for followup questions.
Herpes sores may be very small and only get a tiny fluid filled head after a few days, not a pus filled head. They may never actually look like blisters but may just crust over into a scab. Many people do not get flu symptoms unless its a very severe case.
Still good advice to have the lesions cultured for hsv and bloodwork obtained.
If you are diagnose with hsv, this is a good website as a resource. Good luck.
