<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had a terrible reaction to pine nuts - firstly a very metallic taste in mouth and everything tasting bad - soapy and metallic - this lasted about a week with v bad symptoms but Now - 3 weeks on I still have a metallic taste in mouth and feel very unwell - lethargic, tired - could this still be the pine nuts?  <response>: Hi, This is a not so common, yet one of the possible sequela of ingestion of pine nuts spy a Chinese variety, that has surfaced nowadays known as pine mouth syn Chat Doctor. It causes this metallic aftertaste. But rest assured this is self limiting and would go away soon. Try taking a lot of juice fluids. If the symptom doesnt subside by 1 week, kindly get it re-evaluated by a physician. Regards.
