Pain in right testicle

Dear Doctor, I been having pain/uncomfortable sensation in the right testicle(if you hold the testicle from bottom, its on the top of it where your fingers meet , there you can sense 2-3 nerves like and exactly there) and this discomfort sensation extends to lower abdomen (pin pointing to lower hypogastric region, that can be called, may be lower abdomen) and then same sensation radiating back towards right kidney. This pain is not continues, its off and on. I been to english/allopathi doctors and they initially they gave antibiotics for 2 weeks, still had same problem.Then they took scan and all found all good except calcification of very minute size and doctor said its nothing to do with it. Then doctor asked me to do one yoga pose called butterfly yoga asanam, there by relaxing the cords going toward back. I did but yet again this issue comes back again.
This comes especially when I masturbate. But having said that I am used to this for long , and I never had this before. But in the recent past what I observed is this comes back when I masturbate.Earlier it was not like this !! Yes one clue is once by mistake I hit my testicles hard while catching falling curd packet as it slip through. This was the starting point for this problem.

Please help me solve this issue.
