This question is about my husband. He is 41, 5'10", 200 lbs, works out with weights, eats very healthy and has no diseases. About 3 weeks ago, he had pressure in his chest after he ate around 1:00 pm and it had to come back up. He could not keep anything down until that night. Shortly after, it seems like it has gradually got worse. Now it isn't bad enough to come back up but even when he drinks water he can feel some pressure. He eats more slower too even though he never ate fast before. This past weekend, he had a fever of 100. Also, he seems like he can't hear as well as normal. What do you think this is and what can make it better?
