Lifted a heavy object and felt tingling in left testicle. local doc says no hernia, just pulled a muscle down there. but scrotum is tight/retracted?!

Hernia to be.: you did stretch the muscle around the area where the cord pass. there is a natural opening there called the ring, there is internal, and external. the ring might becomes wider after heavy lifting, which will promote the making of a hernia in the future, the doctor might not feel a full blown hernia yet, that why it called, a hernia want to be. apply heat, take ibuprofen, and avoid heavy lifting.
