If it is noticeable I would sedate. Make a 1/4-1/2" incision at the lowest spot, so if it begins to refill it automatically drains. I always flush it with hydrogen peroxide/iodine, which helps get into deep pockets of infection. I treat with 6cc/100lb of nuflor SQ. Nuflor is great for fuso, pneumonia, and bone infections. I also treat with a good dose of penicillin. this generally clears it up first time around. Any other questions give me a call. Ryan
