Doppler scan shows mid left hydrocele with loose scrotum. Is this normal?

Hello doctor,

I went for Doppler scan because I feel a small tiny seed inside my scrotum sack. The scan says everything is normal. Nothing is found, testicles are fine but it says mid-left hydrocoele found. Doctor said, no need to worry and it is no cause for alarm and that I can drain it if it got bigger. I went home. After five days, I notice a swelling that is not round in shape and close to the left testicles. The urologist did another scan for scrotal Doppler. The report is the same as the first one. Only a left mid hydrocoele was found. The doctor said, he is surprised that the scan has not picked up varicoceles. Because he noticed left varicoceles when he feels it. I can feel the right varicocele is small than the left varicocele. He asked me to go to another hospital for a scan and mostly they should check for varicoceles. Surprisingly, the third Doppler scan for scrotal in another hospital seen nothing wrong, and the investigation was normal. The urologist says, since the three reports have picked up nothing and no varicoceles are found, he could not operate on it. That this is because the varicocele is not large enough to cause problem for the Doppler to see.

I asked the doctor whether I should go for a semen analysis to see if the semen is normal. He says that is a good suggestion to rule out every suspicious of varicocele and my sperm count is normal. I ask him about the swelling close to the testicles, he said, that is normal and I should relax and it will not affect my testicles. Do you think I should be relaxed about this? Is the doctor right? I have a very loose scrotum sack. Is this normal? The scrotum sack reduces in size only when I feel like using the toilet to pass out stools. Is this normal?
