Thank you for your question.
I am Dr Saha, I shall try my best to help you.
There can be collection of fluid or hydrocele.
As it is not painful, there is unlikely to be an infection or inflammation.
Sometimes, it can come from a growth.
I would suggest to take an examination by doctor.
He can take an ultrasound examination to know the nature of the swelling.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
