Just wanted to update. After a lot of improvement the horse went back to 5/5 lame last night with heat/pulse in toe. This morning leg was swollen, mild temp. Vet was out early and she found two abscesses getting ready to blow. One at his toe and one big mushy spot at coronet band on heel. Vet is confident it's abscesses and said that heel abscess of probably the result of a hard blow and bruise. So now horse is wrapped and all that and I am waiting for these to start draining. I have the horse booted and with access to turnout so he can move if desired. Poor guy! I hope this is over soon. I have a lot of new gray hairs!
Abscesses are draining. Horse is super happy and by yesterday was cantering in his little pasture. The abscess in his heel was huge, the opening along the coronet band is nearly 2 inches long. I'm relieved, it's been a long scary week, but we still have some work ahead getting these healed up.
