My chicken has feet problems.

My leghorn has swollen Bumblefoot on the top and bottom. The top is the worst but the bottom is somewhat swollen. We went to the vet and she is taking 2 ml of cephalexin twice daily. This recent vet has opened it and gave us medicine but the one we took her to weeks prior only opened her on the bottom and didn’t give us anything for her expect soaking in epsom salt and betadine. It’s been going on for weeks now and the vet wants her too come in every week, she has only seen the vet twice and I like this one. The bottom oozes some pus when squeezed because of the scab. Is there any way to make it go away faster? I am worried about her because she is one of the older birds and very loved.
