Leg injury, Duck help

[AMaggio]

Hi all, I have a four month old Pekin/Mallard mix who has suddenly started limping. I've checked the foot and leg twice now and I know it's not Bumblefoot, there's no injury in sight but the ankle feels a bit swollen compared to the other leg/ankle. I can touch it and it doesn't bother him, he doesn't struggle when I feel around but I want to do what I can to help him recover quickly. This happened to another of my Mallards and she recovered on her own. He's eating normally and other than resting in the yard a little more often than usual he's his normal flirty self. I saw someone suggested letting him soak in an Epson salt bath in a different forum. Any ideas how to bring the swelling down?

Salt soak and B complex is standard recommendation. Unless the experts suggest more.

X2 what @Texag87 said along with rest. And Epsom alt is also a laxative so don't let him drink the water.
