Wrapping can moderate/minimize the swelling/edema when long standing or idle. Without wraps, my question, in some instances, would be cellulitis: hard to heal. There are schools of thought that also lean toward the prevention of laminitis thru wrapping but not sure that would be an issue here, however, we talking horse: one never knows for sure. For every ten yesses, there will be twelve nos.
SmcGee, might want to reconnect with your vet…What was the illness that your horse suffered (glad he is better but hoping this leg issue, too, shall pass)? There might be repercussions due to the illness more than from the work itself… for now, until the situation is a bit more defined, I would limit the horse’s activities to an easy hand walk/turn out programme along with cold hosing.
Sure there's right and wrong but mostly there's just a whole lotta different.
