Thank you. I am very happy with oyur answer and I will make an appointment for these tests to be done. What symptoms would I feel if it is this Achalasia? I have trouble swallowing when drinking - my partner teases me for sounding so loud. I kind if gulp when I drink. I also choke on my food every so often and in the mornings it takes a few hours for me to clear my throat. The pain I get where the sphincter is located is not often - what causes the pain?
