Lately I've had a sensation in my throat like something is in the (like I need to burp it up but nothing comes up) also now and then makes me feel short of breath.. I do have gastritis but don't no if this is related it's really annoying me now and in havent slept for a few days because of it ..

It's just a weird sensation and I keep swallowing a d coughing yo move it but nothing moves ??
