question: I have discomfort in chest. Not constant. I dont feel out of breath or anything. Its like sinus pain in chest. Esp after cold drinks. Eating food does not give me discomfort. I do have more difficulty swallowing liquid though. Esp through a straw as well. Seems to be behind sternum inside. I tend to drink co!d or icy drinks, as its easier to swallow liquid. Hot or cold. Lukewarm is much harder ti drink.
