Ouch! I had an infected abcess late last year for weeks. It wouldn't respond to antibiotics and I ended up in A&E being stuck on a drip and having it "sorted" by the nice surgeons in the emergency surgery ward - OMG, such a relief when they did it.
From my experience, having left the hospital being told to get in touch with my GP as I needed the would packed (I'd stay blissfully ignorant, doesn't hurt so much, more just gross) and dressed at least every other day until it healed enough.
I then found my GP practice "doesn't do wound care" so had to try and find another clinic who did and could fit me in at very short notice, given it had to be redressed the next day, who then told me I should have been given a prescription for surgical packing and dressings (you don't get the packing over the counter in Boots!) as they don't just provide them but did as a "one off". I was then told I had to go up every day for it to be checked and redressed for about 5 days.
I ended up having to speak to the hospital who were great and arranged for me to see the nurses at the hospital walk in clinic every day after work for it to be sorted.
Thought I'd warn you so you know what to ask, just in case you end up with a similar faff.
Oh and I can speak from experience that after having the procedure late evening under the local I opted for (general meant days in), going into work for 8am the next morning was really not such a good idea!
Feel better soon, abcesses are evil x
