I haven't eaten much today, not for any real reason, but when I ate a bagel, within about 20 minutes there was something that felt like incredible pressure building at the bottom of my stomach. It felt a bit like hunger, I waited for it to pass but it built and built to an excruciating pain, just below my breastbone radiating into my upper back.
I ended up tearing my bra off (not as erotic as it sounds) and crouched hunched over on the floor. When deep breathing exercises and sips of water didn't help, I lay down on my side - and it eased within minutes.
I sat back up again, and in 20 minutes had another intense wave. I quickly lay down again, and it eased. Since then, it has threatened once or twice and I've felt uncomfortable, but it hasn't built up as badly as the first two episodes (each lasting 10-15 mins).
I don't feel in the least bit unwell, no fever, no nausea or vomiting, no diarrhoea (faintly upset tummy earlier but I have IBS anyway). I have no gallbladder, and this pain was far worse than any of my gallbladder attacks. I do suffer from oesophageal spasms, this was very similar but much further down - around my stomach, not my gullet.
Any thoughts? No point speaking to a GP unless it goes on for a week or there are other symptoms. I've eaten a bit of dry toast this evening and had no repeat performance so far...
