Oh @mrbrandon, I am sorry you are experiencing this. With some of the symptoms that you were experiencing that you thought to be COVID related, I would definitely get checked out by a physician sooner rather than later. When your overall health is concerned, it's never too early to see someone!

There is a member that posted a discussion with similar symptoms, and I don't want to alarm you, but it's better to be safe than sorry. Masses in the testicular region could always be benign, but you need to have them checked to be sure.

There is also an article with Mayo Clinic that may deem useful. Scrotal masses - Symptoms & causes: https://www.mayoclinic.org/diseases-conditions/scrotal-masses/symptoms-causes/syc-20352604

Brandon, have you discussed this issue with anyone? Friend or family member?
