I noticed one of my horses had the start of an abscess at the start of last week, I treated it with soaking it in ebsom salt and wrapping it with an antibiotic and keeping him in a dry area [stall and arena]. I got the farrier out as soon as possible, middle/end of last week, and that helped him. I then soaked it again and re-wrapped it. He's doing better then he was but he still looks a little sore and will limp for a couple of steps.
What else should I be doing?
