Bumblefoot bad enough for a veterinarian?

[ChknLadyBawk]

Hello. I have a Deathlayer hen that has bumblefoot on both her feet. The pads are swollen, and while the left foot appears to stay the same, the right foot has swollen even more since I started treating it four days ago. I have her on a ten-minute Epsom salt and Chlorhexidine soak every day, then spray her foot with antibacterial spray for chickens, and afterward I use medical tape and gauze pads to cover her foot. Do I just need to up the amount of times I soak her feet per day, or do I need something stronger to treat this?
Here are pictures of her feet.
