Hi!
I'm not sure what medical specialists you have in China, but I would look for a doctor who specializes in Gastroenterology - the doctor with the experience in digestive system. You may have something as simple as acid reflux or something much more complex, but you need to be evaluated by a doctor.
good luck,
Lulu
Yes, I agree that the first thing to do is to have heart problems checked out. This is important!
Other than that, your symptoms don't sound a lot like MS. Have you seen a neurologist? I would suspect that your digestive system may be the cause of your problems, but you need to be thoroughly evaluated by a doctor or several doctors.
Good luck to you.

I am not a doctor. I would get the chest pain figured out first, on the chance that you could be having a heart attack. Are there some specific symptoms that you think are neurological in nature? lois
