Hello Doctor, When I get sexually excited , after some time the pain starts from lower abdomen to left part of  urinary bladder and goes down to the testicles. That pain discomforts me. I feel like testis became heavy. If the testicles feel any jurk at that time it hurts a lot and I feel discomfort while walking. But if I take a sleep the pain goes off the next morning and I feel normal. Why is this happening? Is this a serious issue? Whom should I consult? Please respond to my issue and help me out so that it can be treated if its a serious issue. Thank you
