Attached is orchitis with inflammation and enlargement, accompanied by pain. What medication is best to take?

Patient's question:

Inflamed and enlarged right testicle with pain, and causing pain in the right groin area
This condition started just two days ago, and I haven't gone to the hospital yet

Doctor's answer:

Your condition may be testitis, which is usually caused by bacteria and viruses. The testicles themselves rarely suffer from bacterial infections because they have a rich blood and lymphatic supply, making them highly resistant to bacterial infections. Most cases of bacterial testitis are caused by inflammation of the nearby epididymis. It is recommended to treat it with intravenous antibiotics.
