I have had nausea on and off with my IBS for a while now. However, in the past week the nausea feels different. It kind of feels like there's something actually stuck in my throat. It has been there for about at week and nothing I do gets rid of it. I don't know what can be causing this, so I don't know what to take. I've tried pepcid, thinking it might be from acid reflux or something......but it hasn't helped at all. The only thing that gives me slight relief is lying down flat on my back. Has anyone else ever experienced anything like this? What gets rid of it? I can't stand it anymore.
