Perianal abscess. With medicines?

Hi I had undergone 2 surgical drain for the abscess- one in July and one in August. The wound is still not healed and there is still puss oozing out and I have pain which is on and off. I am looking for a solution to this without undergoing another surgery. Can this be treated with medicines? It's almost 3 months that I am undergoing this pain and is very much uncomfortable for my daily life. Please suggest if you can help me out with this (preferably without another surgical drain or a surgery). Also according to the gynaecologist that I was consulting, I have external piles. She said it's not complicated and won't do much harm. But when the stool passes there's pain in the anus and discharge of puss from the abscess wound. The wound is 75% healed but still the puss comes out. Please help :/
