Thanks for using Petco Pet Education Center, formerly Petcoach! It is not possible to know what this is without an examination. This lesion you describe could potentially be something like an abscess for example. However, other things are possible. I recommend that you have Leah evaluated by your veterinarian for further assessment and treatment. If an abscess was noted, further local therapy with drainage and antibiotics would be recommended. Good luck and best wishes!
