Over last couple years I have had occasional feeling of muscles not working properly when swallowing. Over last year this has progressed to discomfort in lower oesoephegus when swallowing liquid or food.it feels like food cant be pushed down! Over last 6 months I have started getting severe spasms when eating or drinking, on occasion. That has happened twice over last week and chest is still painfull. it is the most horrific feeling and feels like My chest has cramp. It lasts for about 5-10 mins but is really severe. 10 years ago I had neck surgery (to remove green field filter) and sternotomy , which has resulted in Phrenic Nerve damage and paralysed hemi diaphragm. Could this be causing my problems? I am awaiting an appointment with Gastrologist at moment but there is a 4 week wait. Any ideas about what is going on ?? Any one with similar problems??
