Hi,
You should meet a
dermatologist around you and seek his/her help.
From the history, it seems you could be having any of the following: recurrent furuncles, acne inversa, crohn's disease, warts, fistulae and chronic abscesses.
You may need antibiotics and some immunosuppresant medications.
At home, you should use an antibiotic cream which contains
fusidic acid or
mupirocin unless you are allergic. Keep the area clean and dry and use some antifungal powder to prevent
fungal infection. Do not wear tight clothes and underwear.
Hope this helps you
