A 16-year-old boy comes to the emergency department complaining of severe pain in his left testicle. The pain started about an hour ago and he rates it as 10/10. He has experienced this pain three times before, but he has never sought medical attention as it usually goes away within an hour. Upon examination, there is swelling and redness of the scrotum.
After being admitted, the pain and swelling begin to subside.
What treatment should be administered in this case based on his presentation?
