Hi ! From the history , it seems that possibly you have got a recurrence of the hernia
, which though less frequent now a days does occur. The vomiting
sensation which you have got may or may not be related to this. It may be an independent entity. I would suggest you to go for a good scrotal support, avoid prolonged standing, or lifting heavy weights. If your symptoms do not abort, then you have to have a second opinion
by another surgeon who after clinical examination may advise you to go for a CT scan
or an MRI
of the area for further needful. Wish you an early recovery.
