Hi, i am 25 years old male, past week i felt pain in my left testis and consulted a doctor, doctor suggested it might be because of some pressure to testis, or if motion doesn't happen it may pain, for the next few days i did not feel any pain, but since yesterday i feel dull pain in testis,i manually checked my Testis for any damage inside, but there weren't any such thing. The pain will come and go Can any one tell me why is this happening? Is it something serious?
