I have left testicular pain for the last four years. Can excessive masturbation be the cause?

Hi doctor,

I am 29 years old and I have been suffering from left testicular pain for the past four years. I went to the hospital when it began and an ultrasound was done. It was found normal in terms of size and texture. It does not indicate a hydrocele. Before doing an ultrasound, urine analysis was done and it was fine. A blood test was done and the doctor told me that it is fine. After that, I did an ultrasound and it was normal. When I take medicines for left testicular pain, it disappears and after four months, it recurs. I did an ultrasound and urine analysis again and the results were normal. I practice masturbation thrice a week. When I was in school and college, I use to masturbate every four times a day. I got addicted to it. What is the problem? Could I have this problem due to excessive masturbation for many years? Although the scan reports are normal, when I feel the left testis by touching it with my fingers, I can feel some coiling at the back. Again, my penis and left testis get numbness.
