I am 5 7 , 145lbs and I recently quit smoking a month ago and I have a dull pain on the right side of my throat along with what seems like food caught in my throat, mild ache under my right jaw, discomfort behind my right ear and into my right shoulder , occasional buring throat with a nose bleed (right nostral) that comes and goes for the past three weeks. I spit a little blood in the morning, but I think that is because of a nasal drip from the bloody nose which is usually in the morning. Could this just be a sinus infection? I have suffered from what I was told migrains that effect the right side of my head in the past.
