hello dane i thought i would share that i'm also going through the process of getting tests done for my tight chest, feeling as though my esophagus is very tight all the time.
are you also getting food stuck?
do you have constant belching?
if so it's could be dysphagia. personally i'm finding my dysphagia very difficult to deal with because the constant pressure in my chest makes me unable to concentrate on anything else, and eating makes it feel much worse so i've lost 8kg of wieght in 3 weeks. i'm booked in to get an endoscopy by a gastro specialist so he can hopefully find out whats going on.
Acid Reflux (GERD) will cause what you are experiencing. Always make sure your head is elevated at night, and try some Prilosec, which can be bought over the counter.
The next step is to see a Gastroenterologist so he can view your throat and see exactly what may be happening. If he finds nothing wrong, you may want to see if it's anxiety which can also cause these symptoms. Good luck and take care.
I had similar feeling of pressure in my esophagus. It felt as if my esophagus was full with food up to my throat. I could eat and swallow and it would go down. I tried burping but it didn't help the pressure feeling. I wasn't having heartburn. It turned out to be the welchol I had started on to decrease my cholesterol. I felt bloated, constipated, a little dizzy and a fast heart rate every late afternoon and evening. I was very fatigued and just felt lousy all over. I have to admit that the pressure feeling in the esophagus was the scarriest.
