Hernia is a possibility with what you are describing I agree
So I would like that you should have it checked.
Even if it is a hernia and it is not causing you any symptoms, you can travel with the hernia.
If you can attach a picture here of the swelling that would be nice. It would give a better idea.
Let me know if you have more questions.
I would appreciate it if you rate me services when you are done.
