Over the last few months I've had a number of uncomfortable bouts of a kind of indigestion-like sensation - like mild heartburn and the feeling that something is stuck in my throat - combined with a tingling in my mouth. Anti-acid tablets don't help and I'm a non-smoker so it can't be anything to do with tobacco. It seems to last for several weeks at a stretch then disappears again for another few weeks. There's no pain or difficulty in swallowing just discomfort and, of course, the worry as to what it might be.
Any ideas or suggestions would be gratefully received. Thank you.
