After using sanitary napkins during menstruation, my vulva itched, and I felt too hot to wear tights. I felt allergic, but erythromycin didn't get better after using it for two days.

Judging from the symptoms, considering the possibility of allergy, it is suggested to stop using it actively, and appropriate antiallergic drugs can be selected for treatment, such as loratadine or cetirizine, vitamin C, calcium gluconate, prednisone and so on. c

Suggestion:

The Cd suggests that you take active anti-allergic treatment when necessary. If you don't get better after treatment, I suggest you go to the hospital dermatology department for active treatment.
