I made an
amazing lentil soup tonight (the recipe is on the "basic questions about lentils" thread

)
Within 30 minutes of finishing, I was having stomach pain (both just a general uncomfortable feeling and a bit of stabbing pain), felt very gassy and was visibly bloated. I thought I just ate too much, but 1. I didn't eat
that much and 2. it felt different from that kind of discomfort.
The only thing in the soup I don't eat on a regular basis is lentils. Last time I ate them was 6+ months ago and I can't remember if I had this kind of reaction.The way I felt reminded me of the way I have heard it described when people who are allergic to wheat eat it - bloating, gas, and pain. I did a bit of googling but everything I found described anaphylactic reactions to lentils because they are a legume. Is it possible that the lentils are what made my stomach hurt, or just a fluke?
