Forgot to add that my BP was also slightly higher than normal. I was 140/90.
And Doctor was saying that all was because of gastric problem
If ECG turned fine it must be another cause. Possibly anxiety or some other cause. Most missed diagnosis is anxiety/depression and OCD.
Try looking into symptoms of fibro, and cfs I suffer with most of what you describe
If you doctor said it was a gastric problem, what tests did he/she do to determine this? What diagnosis did they give you? Did they give you any medications or tell you to change your diet?
Do you have a history of gall bladder disease? Are you more comfortable in a certain position? If so, what position? Are you having an nausea, vomiting, diarrhea or constipation?
Did the doctor do an EKG/ECG or not? If not, with your symptoms, I would seek medical attention elsewhere, even if you have to go to the ER.
