PROVIDENCE was diagnosed with acute right hind cellulitis/lymphangitis. His condition deteriorated despite aggressive treatment with ceftiofur, gentocin, anti-inflammatories, local hydrotherapy and physical therapy. The leg had profound swelling from the hoof extending proximal to the prepuce and ventral abdomen. The limb was diffusely wet from leaky serum. Providence was nearly non-weight bearing on the leg.

Providence was treated 10 times with hyperbaric oxygen over eight days, while continuing similar traditional medical treatment. Fourteen days after initial therapy, the swelling was resolved. He was sound and returned to athletic training.
