At the end of August, i got really bad toothache - so in the end had to book an emergency appointment at the walk-in clinic in our local town. They told me that i had a badly broken tooth, so put me on Ibuprofen, Penecillin, Amoxicillin and Co-Codamol, and said that they would send me a follow-up appointment to see the consultant and then have the tooth removed.
Anway i got my follow-up appointment to see the consultant (the man who was going to take my tooth out) which was on Wednesday this week. But a few weeks before i had to go to this, i got a gum-boil on my gum next to the tooth. On Wednesday i had an X-Ray and was prescribed some more antibiotics until this morning (Friday) when i would have the extraction.
So i've had the extraction and all went swimmingly - considering how scared i was.
The thing is - looking at my gum even though i've had the tooth out - the gum-boil is still there

Plus the tooth above the infected one which i've had removed seems to have started throbbing a little bit - like not really bad toothache or anything and there's no sign of decay, but there has been a dull ache in it.
When should i expect the gum-boil to disappear?? And why would the tooth above the one i've had removed now be throbbing on and off??
