Could sinus drainage be giving me nausea and stomach pain?
I've been having trouble with nausea, stomach pain, and stomach bloating off and on for several weeks. It usually goes like this: I feel sick. Then in a short while my stomach starts to hurt, and some time later, I have abdominal bloating. The only common thread I see (other than stress) is that often when this happens, I am also having lots of sinus drainage. Anybody familiar with this?
