Experiencing Pain In Penis Which Is Spreading Till Stomach

Hello Doctor,
I went really rough with my penis during masturbation.And got huge pain on the left side of the penis.Met Urologist and had undergone Ultrasound KUB, Doppler Scrotal,Penile Doppler,Uroflow,Urine Culture,MRI and nothing was detected.I am getting shooting pain starting from the penis to the stomach and leg and it is unbearable.Today I met the Neurologist and he observed and conducted Nerve Conduction Study for the lower limbs and it came normal.It has been bothering from 4 years.Stille did not get any solution.Not able to concentrate on my day to day work and personal life. Please help to get normal.

Thanks,
Bharath.
