Nope - but I remember my mum having it when I was a kid.

She described it as if someone was cutting her side, twisting the knife. However, it wasn't constant - it came in waves, a big attack in the middle of the night, then just a dull pain for a day or two, then another big attack.

I remember being waking up in the middle of the night to the sound of mum cursing and wailing, and finding her doubled up in her bed - and if nothing else, she was tough.
