Is this anything to worry about?

You could be suffering from reflux disease but hey, don't be getting upset at that. Have you tried any remedies like Gaviscon, it helps to settle you down a bit. It could be worth you paying a visit to your doctor though because i had reflux disease a few tears ago but had to have some surgery to correct it, i am fine now and can eat anything. Don't let this go on without doing anything about it as it is an unpleasant thing to suffer from. Good luck..
