I used to get pain like that with my reflux---I rarely got the burning in my throat---but when I got pain like that it would usually last for awhile, not just a couple of seconds.
When was ur last visit with ur GI Dr? Many can experience vagus nevre issues with GERD but u need to allow ur Dr to DX and suggest treatment options. A site like this is great to commiserate and share info, but we can not DX u.....
Since u have a history of GERD issues, u may want to keep a journal of what u eat and how u feel, log issues like the one u mentioned to see if there is a pattern...it may be eliminating something from ur diet, and a journal may help ur Dr pin point what is going on.
Continue to exercise and eat healthy and avoid the foods u know are tiggers.
