Thanks for posting your query.
Let me correct one thing: Testicles are outside the body in scrotum while stones are common in urinary tract
Testicle problems may cause abdominal pain
and generally associated with tenderness along with fever.
Pus cells also may be present in orchitis
You should consult with urologist
and should go for thorough check up.
You should take complete antibiotic course for rapid and better recovery.
