The degree varies from subtle to non-weight bearing. The pulse at the fetlock is usually pounding, and the foot with the abscess will be warmer than the opposite foot. The point of pain can be located using hoof testers. The wound or point of entry may not always be visible since some areas of the foot, such as the white line and frog, are somewhat elastic, and wounds in these areas typically close. Sometimes pain will be noted over the entire foot.
Treatments work best at the first sign of lameness, before the gravel ruptures at the coronet.
Treat a simple subsolar abscess by opening and draining the infection. The opening should be large enough to allow drainage, but not so extensive as to create further problems. Drainage can be speeded using a poultice for the first 48 hours. The hoof is kept bandaged with a suitable antiseptic until all drainage has ceased and the wound has closed. At this point, a small gauze plug, held in place with glue, is used to fill the opening.
