I'm 38 yrs old, suffering from sinus in my nose. Apart from this I have been observing for last 1 month that when I ever I have little heavy meal especially non veg, it seems after some time that my food is not digested. And my nose stinks. And it feels little bit of nausea but not to that extent that could lead to vomiting. Is this because of sinus? Or some stomach infection? I'm taking homeopathic medicine for sinus and allopathic for my blood pressure.
