pls i just did a bilateral varicocelectomy,to my surprise when i read it online i learned they will make a small cut at the scrotum then do the surgery from there, but my urologist, just made 2 small cut below my abdomen, both left and right side, i went home 2 hrs after the surgery completed, my problem is i still have the same feeling i had before going for the surgery which having small pain in my left testis sometimes on the right which the ultralsound came out that it was varicocele, now a day after the surgery i noticed my scrotal sack, has now become biggier , like it has expanded, my questions are :

1 ,could it be cos i just had the surgery and the scrotum is getting healthier cos it was like shrink stuff before or is there a cause for alerm?
,2,why am i havin this same feeling around my testis again, especially on the left side though the pain is not much as it was before the surgery,
3,why was the approach of the surgery different to what read online, why made the cut on both side of my below abdomen instead of the scrotum.
4,thus the sperm increase automatically without using any sperm booster ,if there is any?
