This sounds more like a sprain than an abcess to me.
Sprains will tend to cause more pain the 2nd and 3rd days because of swelling and you usually see gradual improvement after that.
Abcesses can often cause pain more suddenly and pesky ones can take weeks to come out, but once they do the pain relief is very quick. In my experience, the worst/most painful ones are the ones that work up the hoof and drain at the band.
Either one can cause a horse to go three legged lame.
I would continue to poultice, but would also ice/cold hose the leg and limit movement to a small paddock for a few days in case it is a sprain.
We typically avoid pain medicine because it can mask finding the source of the pain, but for 3 legged lamness we will give bute for a couple days. Since it's an anti-inflammatory, it helps a lot with any pain from swelling.
Good luck. Lameness can be so hard to diagnose and breaks your heart to see them hobbling around.
