I am so glad you got it taken care of! Clearly it was very badly infected. Abscess surgery is out-patient surgery -- your day-surgery? -- meaning no hospital stay. I can only think you needed heavy antibiotics because it got so infected or maybe something else was wrong too. I don't know your situation or what is going on with your life, but please, please don't let an abscess go so long next time!! (maybe there will be no next time!!) We on this thread recommended quick treatment for a reason! I know it seems easy to deny them or try to ignore them but in my experience THEY MAKE YOU PAY!! :-( I really paid when I ignored my first abscess. I know I am coming down hard on you, but please know that it is because I am just re-living my own painful, painful experience and wish you weren't going through something similar now.
Isn't it amazing how much better you feel once the abscess is gone!! I just feel less "toxic". I truly am praying for your quick recovery. Just keep an eye on the tissue down there, especially if you have cellulitis -- that and a bad Dr. very neary killed me. But it sounds like you have good Docs who are taking good care of you. Healing will be slow and there may be set-backs. But just relax, consider this time as an extended vacation, and know that it will get better and better!!
As to whether abscesses can form elsewhere, I'm thinking the answer is "yes", but I have no experience to base that on. And I don't want any, thank you very much!!
