Abscess Eruption

Abscesses can exist invisibly and without symptoms, but they can also be painful.  Mysterious lameness may be attributed to an invisible abscess.  On white hooves or soles, an abscess may be visible sooner.  Abscesses work their way out of the hoof capsule; through the sole, over the coronary band and sometimes right out the side of the wall.  (shown in picture)  As they work their way out, pressure builds and pain may increase.

Movement of the horse promotes movement and eventual eruption of an abscess.  Movement may be difficult for the horse, and you want to be sure there isn't something else to blame for the lameness before encouraging too much.  Once an abscess erupts, it is important to keep the opening clean and allow it to completely drain so there is not secondary infection.
