I've had cameras down top and bottom end, but all clear, so put down to functional problems. Concern was shown by the GP when I told her I had the oesophagus spasms when I ate meat or fish when presented whole, but not if cooked till very tender in liquid. How this ties in with the intolerance issues with wheat I have no idea. I have been seeing Body Stress Release practitioner for the past year or so for other reasons, but mentioned this problem to her. She found the muscles round that area are very tight ( I can't bear wearing anything round my neck and even touching the area is uncomfortable.) She has been working on the muscles, which I hate, but has really helped. I can eat tender chicken and even home made hamburgers now. My theory is that I held myself tensely all my life, maybe as an emotional protection from child hood experiences. No longer needed, but a habit very difficult to break, but I think the Body Stress Release treatment, along with yoga and even singing is helping. My dentist I formed me that my teeth are wearing down due to grinding my teeth. I had no idea, but now wear a mouth guard at night to protect what is left. The things we do to ourselves!
