You may not be having achalasia , rather it maybe what is called diffuse esophageal spasms
, as this causes the symptoms which you are complaining of. Please dont worry , as this has to be confirmed first with an endoscopic evaluation and then can be treated. Meanwhile i would advice you to avoid hot and spicy food , and take a light diet.
Please get back to me with the endoscopy
report so that i can help you.
