ok not quite the same but my cat had an injury on her belly.
It was a bruise from trying to get over a fence while a dog was attacking her. The vet said when i was concerned about the bruise being so swollen that we needed to bring the blood vessels to the surface to heal. So we were to use a hot water bottle on her bruise 3 times a day for 15 minutes at a time. We were lucky she liked the warmth, our other cats would not tolerate that at all. But maybe that would help your healing too, and Arnica is awsome! I can get mine at Ralph's supermarket. Or my healthfood store.
Blessed are the flexible, for they shall not be bent out of shape.
