Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This swelling could be caused by many things but the most common would be an abscess which is an infection in this area. This would appear painful and warm. This would need to be lanced by your vet. For now, apply hot compresses to this area every 4 hrs which will help draw any infection to the surface where the pus will drain out. I would hold off on antibiotics until your vet can examine this area. Flies are a common vector in this area to inject bacteria under the skin causing this abscess. It is not serious unless it turns out to be a large tumor, which is also possible.Does that make sense to you?
