A clear tasteless fluid is likely mucous or saliva. You might have an esophageal dysfunction, obstruction that did not let the "sticky rice" move down. Stomach juice is usually very harsh and sour.
This fluid could've triggered the spasm. But again, once the ENT clear you, you might want to discuss about the intestinal issue. Someone could order an esophagram - where you swallow food and see how it goes under a fluoroscope, or do un upper GI scope, or get a barium swallow. It can be cheap for the barium swallow, or more invasive like the scope. Depending on your insurance and ability to pay.
Yes I had the feeling that the esophagus (spelling???) is not OK. But might be first the larynx and later the esophagus?
Do you still recommend a esophagram, even if I never had any problems before and now everything is perfect again like always. No problem to swallow anything.
Well I have no insurance at all, but I would have the money.
My idea would be to wait if anything occur again.
Thanks for all the advices/help so far.
