Hi, I went for a back massage today and the therapist felt an airbubble of sort below my left shoulder blade. Each time she pushed it out, I felt air coming out inside me and through to my mouth. The therapist suggested I get hold of a gp as she has seen this once before and many years ago. The patient she picked it up on years ago went to a gp, not sure what they did but western the patient went back to the therapist, the airport was gone, the gp sorted it out. Any idea what this is and what the gp would have done to correct this?
