hi..thanks for using HCM..
you have developed folliculitis
.. infection of the hair follicle..
clean the area with soap, before shaving..
now you can take a course of antibiotics..
if you have coin like lesions, then it could be tinea cruris
, fungal infection
see your dermataologist for the examination and treatment with antifungal..
keep the area clean and dry.. use dusting powder which contain antifungal..
all the very best..
