Groin pain aster for ed ejaculation: burning in the left groin area until the left basis of the penis. No scrotum pain. Can anybody help? I am suffering about this since 20 years. No solution and no firm diagnosis given. The pain stays until a satisfactory ejaculation occurs. I have done any possible lab test, MRI, x-Ray ecc. Nothing abnormal noticed with the exception of a very minimum groin hernia and a small varicocele. I am desperate... Please help! Thanks in advance for your kind concern.
