I hope you're not scared away or just a troll or whatever. I'd really like some updates on him. I really am sorry I can't be of more help but he really does need to see a vet.

Maybe your vet can work out a payment plan? Sometimes people donate money to the vets and it is put into a fund and is used to help out people in need. Maybe your vet has something like that.
Or a local humane society may be able to help?
A credit card?
Something.
Anything.
