I have a very bitter taste in my mouth after I eat, towards the back of my tongue.

For the last 4 days I have had a very bitter taste in my mouth, kind of metallic tasting, towards the very back of my tongue. I notice it a few minutes after I eat something. I read online that this can be caused by eating spoiled fish. I did eat a fish dish at a brunch on Sunday (that had probably been sitting out for 4 hours, but I heated it up in the microwave). My fiancé also ate the fish and he is experiencing the same bitter taste after he eats. A few other things that might be causing this (that were kind of weird that we ate at the brunch) are gluten free muffins and lime water (limes had been sitting in the water for 2 to 3 days to flavor it). We also had some raspberry vodka and club soda (we hadn't had that before either). Should we be worried or will this go away?

    Well, you certainly have been giving your taste buds some stimulating adventures! :-)

    Perhaps some questions are in order:

    1. Do you know the source of the fish? Could it have contained toxic metals? (Quite common when fished from waters where there is commercial activity.) Acute poisoning from various sources can leave a bitter taste in the mouth (acute mercury poisoning, cadmium, etc.),

    2. Could something non-food related be creating this bitter-taste sensation, such as new chemicals in your environment (from, for example, new furniture, carpeting, paint, etc.)? This might cause post-nasal drip or direct irritation from inhaling, etc.

    3. Could this be bitter-taste be acid-reflux?

    There are dozens of possible explanations for this symptom. Perhaps eating plenty of fresh vegetables and fruits as well as drinking plenty of plain water for the next few days will eliminate the source. Otherwise, you can further research causes for bitter taste in the mouth at wrongdiagnosis.com

    Good luck and careful with the fish. Some fish is better for you than others.

    The acid reflux connection hold a lot of validity. And BTW, the taste buds for "bitter" are only located on the back of the tongue. Its the only location you can detect bitter.
