Last year I had an abscess about 5 cm, I had a surgery and now after a year it came back to me and its growing I don't know what to do beside surgery?

Abscess. Abscesses need to be open to heal. May need to remove the cyst wall. Consider washing w/ antibacterial 'hibiclens' 1-2 x/ week to prevent bacteria build up. Wash 2x a day in summer, keep pores open. Change position every 30 min for 1-2 min . Pilonidal cyst needs more definitive surgery f/w/doc
