oh my goodness - yesterday was a big NSV for me - I went on a 10 mile bike ride! I still can't believe I rode that far! My legs were jelly at the end and I am sore today, but it was soooooo fun! Being on my bike makes me feel like a happy kid.
I agree with the advice to consult your surgeon, but what you are describing is very common. I referred to it as a "cramp", some people call it a "pinch".
For me, it would hit about two seconds after taking a sip...one one-thousand, two one-thousand, CRAMP. It lasted a while for me, it went away in week 3.
Definitely run it by your surgeon just in case, but don't stress too much, a lot of us have been through it. Hope you feel better soon!
Just to help you feel better, I did a quick search and found a few examples of other people who had that pain after drinking:
It's super common, but worth mentioning to your surgeon.
