Hi Doctor,
Just tonight I have felt a squeezing pain under my right rib cage....It doesn't feel muscular but deeper. Also, as a side note.. in the recent past, I have been having a heaviness/pressure/squeezing in my chest and sensation sometimes that I am unable to catch my breath. I do have Barrett's esophagus -- so all of these symptoms seem confusing. GI, heart, Gallbladder or liver?? What should be my first steps to seek help?
