Often triggered shortly after eating (15 to 20 minutes
after eating), though not always and sometimes happens without
eating (maybe 10% of attacks). The
pain does not go off to the right, does not go through to the back. It is a clenching / wrenching pain in the centre just under the rib cage.
The pain is intense to the point of causing fainting on occasion. It makes it difficult to breath. When the pain comes, it comes fast and lasts intensely for about 2 hour to 3 hours.
