Thanks for writing here.
It seems you are having bacterial infection like pyoderma
At times they can form deep infection like abcesses ,cellulitis
Do not try to squeeze the lesion.Use hot fomentation which will reduce pain. Sitz bath seems to be effective.Use loose cotton clothes.
Use a good toilet soap for cleaning area.
You need to take oral antibiotics
It will be better to meet your local doctor and start treatment accordingly.
At times such lesion may require surgical drainage so it will be better to start treatment early.Take care.
