Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly an abscess. I recommend that you have her evaluated by a veterinarian as soon as possible for further assessment and treatment. If confirmed to be an abscess this is usually treated by drainage and flushing of the abscess as well as antibiotics. This usually resolves uneventfully. Good luck and have a good night!
