I think the short answer is that abscesses can take any old amount of time they WANT to take.
I’ve had them go anywhere from 24 hours to 6 weeks. On both of my 6-week encounters I did x-rays. The first one revealed a massive abscess in my mare’s foot that wasn’t going anywhere, so we carved it out and went the hospital plate route for a month. The x-rays on my gelding showed nothing. We didn’t know for sure his was an abscess until we pulled his pads to reshoe him 6 weeks after the lameness started and found an abscess that had started in his lateral heel and tracked through his frog, exiting through the medial side of his frog.
So while yes, most abscesses probably come out in the week to 10 day range, a longer period does not mean that it’s not an abscess.[/QUOTE]
This is also true. When I said our abscesses drained after a day or two, that was counting from when the horse turned up lame enough that I had to do something. In every case, though, once a full abscess presents itself, I realize in hindsight that there was a slight ouch or hitch present in the week or two leading up. Not enough to say “abscess” rather than “stone bruise” or just “fussy about walking on gravel.”
I also think some abscesses resolve themselves without ever showing symptoms, until your farrier is trimming and says, hey, there’s a bit of an old abscess track here, interesting.
Also it is true that horses on pasture can get abscesses, limp around for a few days, and then blow them out and recover, sometimes before anyone has had a chance to notice; you see the slit on the heel bulb or the coronet much later.
That said, if I have a horse in a stall, I do find that soaking and wrapping gives the abscess a better chance of seeping out through the frog commissures or at least the heel. If the hoof is hard and the weather dry, the easier route out might be up the hoof wall and out the coronary band, which causes more damage to the hoof wall and is more painful, and takes longer to build up to bursting.
