He's fought through pain before (drill in the neck, getting his shoulder crystals blown up, etc.) and continued to fight on. Being in pain doesn't effect Space Godzilla's ability to fight.
As for bleeding, the regeneration will take care of it. I'm not saying that the leg would grow back, but I am saying that the spots where the bleeding is coming from would be covered up almost instantly.
