Last week i was petting my Nova when i noticed swelling under her chin. It felt like she had a cut that is scabbing over. Upon a closer look it there was no cut and the scabbing appears to be under her skin. I had my friend who is a vet student look at Nova but she had no idea what it is. I took Nova to the vet last monday and he also didn't know what it is. He sugguested a hot compress to reduce the swelling. Since then the swelling has gotten worse and has spread towards her mouth. Im taking her back to the vet but i was wondering if any of you have a clue what it might be. Thanks
