I have an air bubble type feeling under my right breast, after I eat in the evenings (this is my big meal). I'm not a snacker during the day and don't eat a lot during the day. I'm 5'3 and weigh about 140. This feeling is uncomfortable and I feel like I have an air pocket that won't go away. Usually this feeling starts after eating and lingers for a couple hours. This started about 1.5 months ago..... Thoughts?
