Okay MJ is actually doing a little better since this morning. I did an epsom salt soak and his swelling went down a lot. He's a bit more active as well. I think it really helped him.
I went out to get some medication for him as well. I got Lifeguard and Maracyn. I put a half of a pellet in his water and let it dissolve. The guy at the store told me to soak his food in the Maracyn and then let him eat it, but I'm not sure if I should fast him or not. I think this whole episode started because of constipation. And also the packaging for the Maracyn says to put the liquid directly in the water, so I'm not sure if the guy in the store knew what he was talking about.
If anyone knows if it's okay to use epsom salt while treating with another medicine (Lifeguard), please let me know. I don't know if I should continue the soaks.
Any more advice is welcome. Thanks to everyone that has already helped. I really hope my little guy will pull through. He's a fighter!
