So, at the second attempt I managed to go through with a vasectomy about 6 weeks ago.

Last Saturday I was doing a lot of heavy lifting and woke up on Sunday morning with a left bollock that was really painful and sore to touch.
Had to take ibuprofen just to walk properly, did more heavy lifting that day and muddled through.
Woke Monday morning and pain was gone, later that day it started swelling and became painful again.
Went to docs on Tuesday and he shined a light through my bollocks and said I have a hydrocele and it is probably a complication from the vasectomy rather than because of the lifting.

Anyone had one of these? I constantly feel like I've been kicked in the teds, well the left one at least
