Today at school, after lunch, my lips started tingling and they've been tingling all day. And when I lick my lips, it tastes metallic-y. I didn't eat anything that I'm allergic too or touch my lips after I touched something that I might be allergic to so I have no idea what it is. What could it be?
lulabelle answered Wednesday March 22 2006, 12:37 am: Blood cells contain hemoglobin, which carries oxygen. When blood breaks down, iron is released and causes a metallic taste in mouth. Bleeding can be from the gums, sinuses or nose. The taste can get especially bad when someone has post nasal drip and the dried blood sticks to the back of the throat. If bleeding gums are the cause then there is often bad breath associated with the bad taste. Another uncommon reason for a metallic taste in mouth is due to small electric currents in the mouth. When two types of metals are used in two different dental fillings a battery can be created. Some believe that it's due to the mercury leakage from dental silver/mercury fillings. This could create the feeling of tingling in the lips. Many oral or IV medications such as thyroid medicine, penicillin, and lithium can give a metallic taste in mouth. When someone is allergic to a specific food, the food can often be detected even in extremely small amounts. Food allergies, such as with sulfur dioxide (which is found as a food additive in a lot of packaged foods), can also cause this. Some gastrointestinal disorders can be aggravated by food allergies and cause burping, dry mouth, thirst, rectal itching and a metal taste. High protein diets can cause benign dietary ketosis (a stage in metabolism occurring when the liver has been depleted of stored glycogen and switches to a fasting mode such as occurs during sleep, during dieting, and during the body's response to starvation). This has also been associated with a metal taste. So, if you are trying to loose weight you may be taking in too few calories for your bodies needs. This would be setting you up for that perpetual yoyo effect that most overweight adult Americans are suffering from today. As far as the tingly mouth is concerned it could be anything such as that which I mentioned above for example. It could also be a sign of a pinched nerve or even some kind of nerve damage. I wouldn’t worry about it being this too much unless it becomes persistent and then I'd have it checked it out by your doctor. This type of thing is usually nothing to be concerned about. It will probably go away. Good luck to you!
