advice needed

hello :)
my names holly and i am 20 years old, last week i had a hellors myopathy to help relieve the symptoms of achlasia (achalasia), however theses symptoms havent reduced at all, although my main concern is that ever since i have been out of hospital i have had really bad diarrhea , this isnt down to side effects of my medication as i havent taken any since leaving hospital. but this happens with anything i eat or drink. i have stuck to the plan via the dietitian, however as the days go on it getting worse. im very concerned as i get very bad stomach cramps and pain in my left side of my abdomen, bu mainly because i feel sick and weak all the time and lack in energy .. any suggestions would be great and much appreciated :)
thankyou

holly :) xx
