Hi. I Had Nissan Fundiplation Surgery About 6 Weeks Ago.

Hi. I had Nissan fundiplation surgery about 6 weeks ago. I had a bad stomach ache last week and felt the need to throw up but nothing would come out. this made me think and wonder if I ever have a stomach virus, how will I vomit? And what about food piosonong? I'm nervous rhinjong I won't be able to vomit if.
