I have gone through your query. Acute episode of pain is usually seen in testicular torsion
. But you have mentioned that it has resolved and you are experiencing dull pain. This is not normal and it should be investigated. I assume that your blood and urine reports came out to be normal and that is why you were put on adderall(amphetamine
I would suggest you to go for a USG Scrotum
after consulting surgeon.
Do consider a positive feedback as a credit to my work. Let me know if you have any further questions.
