Welcome to HCM and thanks for posting your query here.
you are saying about could be a skin infection
mostly of staphylococcal in origin. It could be because of excessive heat you have applied to the legs while waxing or pulling the hair with extreme pressure. It may cause hair follicle root infection. Roxithromycin
of 150mg , twice a day for 5 days will give you the result. Levocitrizine or Avil can be used for the inflammation or the itching to come down. NSAIDs like Diclofenac
or Dolo 650
can be used twice a day until the symptoms subside. That will reduce the inflammation around the pustules. It will take time for the antibiotic roxid to work. Please look for 2 more days and if the infection is not subsided please consult your GP. Untill then please avoid soap or any chemicals over the boils.
Hope this is helpful to you.
