Has anyone experienced pain/cramping when drinking water?

I had no problem with water pre-op. Now, 3.5 weeks post-op, I seem to cramp every time I drink water... even at room temp. I can barely get in 20oz per day and I know that is not good. Any suggestions would be greatly appreciated. Thank you!!!
