Thanks for the query.
You have developed infected pustules.
There are two possibilities
1. You might have developed furuncles
These are deep bacterial infections.
Treatment is with antibiotics
2. a fungal folliculitis
, as there is lot of itch.
It needs treatment with anti fungal shampoos
Please meet a dermatologist
for exact diagnosis.
