I once came across a poster at my dentist's advising to see a doctor (amongst other things) in connection with any difficulty in swallowing. Curious as to why (why a general advice poster to the public advising this) I read up on the subject and in the course of that came across hiatus hernia (which I had heard of but only now understood). In A Pickle is correct to advise you to see a doctor because (from my reading) the possible effects of frequent/constant reflux over time can be quite worrying.
