Did the appendex hurt? Similar, yet different experience. To comfort you.
I know a littler over 2 years ago I drastically lost weight, (100lbs in 7 months) from dieting. [Yes it was a healthy diet, but since I was really heavy it lost faster than the 2/wk period]
And in doing so, my gullbladder inflammed. From being too used to always being under constant "heavy" foods to not. It hurt if I ever ate more than 5g of fat in food in a 5hr period. Basically I was down to cream of wheat and 0g fat pretzels. more or less.
(Worst case before I kew the issue, was xmas I ate ALOT of fatty stuff, and was in so much pain puking bile. 3hrs hurting so bad I finally gave in and got a ride to the ER to check it out. All tests turned out nothing was wrong. Thus explaining to my doctor we agreed to remove the gullbladder because it seemed like the main cause, even though tests didn't show issues with it)
After surgery I remember coming to, and about 30min later in a recovery room the surgeon shows up and lets me know my gullbladder was inflammed to about 4x the normal size.
It sucked.
So here is to you OP. Hopefully it didn't hurt to bad and are fine in a few days.
