I would get him in to the vet...
If it's bleeding... it might be trama between the nail and the toe/bone where you can't see a break. I would verify that this is what's going on and pursue a treatment plan.
There's other things that would cause toes to swell up - whether fractures in the toe or even tumors in the toe, so that's a reason to follow up with the vet and make sure it's just the toenail you are dealing with.
Keep him on least outside - no running around.
