This is a new symptom that I've been experiencing. While eating, I feel uncomfortable (not necessarily pain) underneath my breast area; up high. Sometimes it even feels like I might be a little nervous. It has caused me to eat less because of this feeling. Even though, I'm not overweight, I would love to drop 10 lbs, so I don't mind eating less. But, I don't want to have something medically wrong causing me not to eat.Any ideas?
