Hello and hope you are doing well.
It could be an allergic reaction if the symptoms have occurred repeatedly with consumption of the same food. Maintain a food dairy to keep track of your symptoms. An allergy specialist may help diagnose.
Hope this helped and do keep us posted.
Hi, I have had these symptoms due to an acid stomach. I don't necessarily get the reflux, but if your stomach is acidic, then hot drinks, caffeine and fatty foods, like cheese or chocolate can cause these symptoms. The acid pressure can move into the throat without you realising it and cause pressure in ears and sinuses and sometimes breathlessness and quick pulse. etc. I would suggest seeing your doctor for some anti acid medication, or over the counter, Gaviscon for instance. Avoid, caffeine, alcohol, especially white or sparkling wine, tomatoes, peppermint and chocolate.
Hope this helps,
