Hi! Thanks for replying. It was diagnosed through an esophageal manometry, I was having symptoms of GERD, I even had esophagitis for approximately 7 years and I was in medication for GERD for almost the same amount of time. After the diagnosis the doctor suggest to make a PH monitory and the results were normal. After all this happen I stop medication and going to the doctors, cause I wanted to take a break since I was not receiving any answers. Then COVID 19 started and all the clinics were closed but a few weeks ago symptoms started to come back again, sometimes worst than it use to be. I have an appointment in December 3 with my gastroenterologist, hope he give me some answers since I feel lost with this diagnosis.
