Is it serious to have a constant bubbling sensation under your ballsack? it happends always every couple of minutes, and feels like it is bubbling under my ballsack

Usually : Usually the scrotum ("ballsack") contains only the testicles and supportive structures. Three other things can appear in the scrotum that should not be there, a hydrocoele, which is a collection of fluid around the testicle and typically presents as a painless swelling of the scrotum. The next is a varicocele, which is an abnormal enlargement of the vein that is in the scrotum draining the testicles, and may present as: aching pain within scrotum, a feeling of heaviness in the testicle or a visible or palpable (able to be felt) enlarged vein. The last is an inguinal hernia, which is a protrusion of abdominal-cavity contents (usually intestine) through the inguinal canal, and sometimes extending into the scrotum. Since the only thing in the above that can gurgle or bubble is intestine, my impression is that you have an inguinal hernia. A physician can tell by examining you, in some cases an ultrasound or ct scan may be required to confirm the diagnosis.
