Hi, yes, I m asking for my boyfriend. He is 52 years old and has been experiencing pain in one testicle at the beginning of intercourse. He likens it to a sharp pain (like when a guy gets racked ). This started a week ago. In addition, he has been suffering from light headedness, chills, headaches and no energy for about 6 months off and on. Could the two be related? He s under a tremendous about of stress, never eats breakfast, and drinks diet coke all day long instead of water, so I thought the latter could be diabetes-type symptoms. Welcome your input. Thanks!
