Hi everyone, I am so glad I came back to forum here. I didn't come for like near a year since last time I posted here. Please help me with my zebra finch, he is my baby, heart breaking see him with toe look like the pic below

I really appreciated it if anyone have ideas what should I do, anything would help. The swollen toe started about a week ago, but worse since yesterday became so huge and look extended from between the nail and the toe itself, I don't want him lose a toe at all

This morning the toe (middle toe) bleeding so I stopped it bleeding so far so good, maybe he caught on wire again today caused the bleed, when he was flying in the cage look at other birds next to him. I now put him in hospital cage with low perch and food on floor, with warm water dish too. For long term what should I do to help, beside I can't go to Vet near me since so far away...is his toe going to heal on its own?
I've search online I thought he got a bumble foot, but I observed it doesn't look like it, should be wounded when he jumped around between the perches, I used manzanita perches and he is the only one in the cage for months. Any ideas? Thanks for your help in advance and I hope see some suggestions soon. I had this bird for about 3 years, first time happened like this. I am worried.

you can see the pic , under his belly white color part still have some dry-reddish color, that was from the toe bleeding and as I held him on my palm carefully earlier I stopped the bleeding finally by put some powder
Thank you very much,
David
