Pain in my left testis

It all depends on how bad your pain is. In young adults and teenagers, complaints of mild testicular pain are common, which without other associated symptoms usually goes away with time. However, it could be testicular torsion if the pain is more severe. In this case, you should see a doctor, as this can lead to testicular necrosis if not corrected in time. Only a doctor can diagnose and treat the problem.
