I have been dealing with one bumble foot case for 10 months now, swelling can take a while to go down. When you remove the scab, do you try to get the core out, if there is one and any other puss?
Treatment includes soaking for 10 minutes in Epsom salts followed by removing the scab, getting out the core, if there is any and infection (white and stringy). Then pack with antibiotic cream (or similar product) applying a small square of gause and then wrapping up with vet wrap. From then on do 10 minute Epsom Salt soak followed by a 20 minute, 1 percent betadine towel soak daily, wrapping and repeating this until the scab drops off.
