I might have a vagus nerve issue, but I'm not sure. And this seemed like the place to ask.
For years I've been having issues with discomfort around my bowels/lower stomach when sitting. If I sit even just straight up for an hour+, it can cause light-headedness, yawning, or even just a sudden, strong desire to lay down and rest.
I've been doing everything in my power to help with potential IBS. Exercise, lots of fibre, avoiding trigger foods, sleeping properly, having plenty of water during the day. And while these have helped a bit, I still get that familiar discomfort.
So I've been wondering if this might also be related to my vagus nerve? Maybe leaning upright to type is putting too much pressure on it? When I lay down for an hour, the feeling eventually passes. And in general I feel more comfortable when laying back in a chair versus sitting upright. Does anyone have an opinion on this, and potential solutions?
