I have had GERD - for many years - but mild. During one episode couple years ago - noticed a stiff tubular lump 2 inch long - just below the sternum. Going down vertically from the sternum downwards. Mildly painful. As gerd improved - I felt the stiffnes reside and did not tend to it any further.
Recently suffering from mild gerd / indigestion. Notice stiffness tubula right below sternum - 2 inches. Its very stiff. Same as before. Will be going to doctor this week. Please suggest any experience or casuses for this condition. Much appreciate.
