I have had Fibromyalgia for more years than I care to remember and was diagnosed in 2000. Wondering if fellow sufferers have a problem with swallowing, choking, constant coughing/clearing of mucous from throat ...morning and night. On Wed. am whilst making myself a cup of tea I tried clearing mucous from my throat which brought on the most frightening choking episode. I ended up on my front lawn croaking like a frog as I could not get oxygen into my lungs. (thinking certain death) After a short while my oesophagus/trachea began to relax and I slowly came round. I am now awaiting to have a camera put down there to see what was the cause. Not the first time this has happened!!!
