If he feels lump in inguinal are ,redness or pus secretion then it can be some disorder that should be treated. Also if he experience sexuall problems there can be vascula supply disorder and this should be evaluated by ultrasound. If he has penis chnages or urinary pain he should do urine analysis co find possible uroinfection. Wish you good health.

Hi! I do not think that there is anything much of concern about about the symptoms of your husband. This may be a hyper activity of the muscles of the scrotum. He does not have any pain, or redness, and so we can exclude any infective pathology. However, he should use proper scrotal support garments whenever he lifts weights and does any kind of strenous work. A proper re assurance will help him. If the symptoms persist or increases with any other problem, he should consult the family physician for a routine check up. Hope this helps your husband.
