Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Without a picture and not being able to feel it, it is difficult to say for sure what this could be. I would suspect that this could be a lymph node based on your description. I would recommend having a veterinarian take a look at this to make sure it is not from trauma or anything infectious. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
