Hi I have oesophageal spasms , these are incredibly painful. The pain builds up within seconds into an incredible crescendo, and then dies down . Similar to contractions when in labour. I have been diagnosed with a condition called Jackhammer oesophagus, and After trying every remedy under the sun, including Botox injections, I am now having P.O.E.M. surgery, scheduled for October. I have learned NOT to eat or drink anything citrus or spicy. I can’t have caffeine. This has been going on for 18months now . Hope this helps !
