Occasionally, but more frequently recently, I get a sharp pain on swallowing liquids. It doesn't happen when I eat solid foods. It starts suddenly at the back of my throat and travels down a little and then disappears. It's as if it goes with the peristaltic movements of the gut. The pain isn't so severe that I have to sit down or stop doing things, but it is quite annoying.
It tends to happen when I drink somethign after not having drunk anything in a while. It doesn't occur at any other specific time.
Any suggestions would be much appreciated.
