Welcome and thanks for posting your query to HCM.
The most important and first thing to tell you is your problem it is not at all herpes
) as hand jobs are not at all or negligible source of any STD’s. Herpes infections are symptomatic with burning itching and pain sensation having multiple small blister
appearing and bursting within 24-48 hours to leave raw area which are itchy and painful. It never manifests as single painless red area. Now the red area might be just because of maceration of the scrotal area due to heat and sweating during fever
. If you find some more red area at same site or other site then should report to us or to dermatologist
and do not scratch any of the area.
Do not become panicky about the general flu symptoms which are just a part of seasonal thing. With best health wishes,
Dr Sanjay K Kanodia
