Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. You must be having varicocele. Varicocele can cause such a pain. It can cause dragging pain in the abdomen and in the testicle also. In my advice you should correct it surgically. Once you correct it surgically all the pain will be corrected. You should wear the tight cotton under garments. This will keep the testicle varicocele under control until your surgery done. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
