Food allergies have been known to cause tingling lips or tingling mouth, swollen lips or itchy skin., This may appear within a few hours after you have had your meals or even a few days. This is basically a delayed reaction occurring. Some other symptoms would include nausea, diarrhea, breathing disorders or dizziness. It could even be caused due to any kind of chemical allergies like hypokalemia, hypocalcemia or a derangement in the levels of phosphate, potassium or sodium. Tingling of the lips or nose, ears, toes, fingers, is triggered by physical as also emotional stress or cold and can disappear in minutes. These can be caused a result of abnormal arterial spasms. Other causes could be due to sea food poisoning like scombroid poisoning, and horseshoe crab poisoning. Seafood that is similar to mussels, clams, oysters, scallops or snails that are contaminated by some poisons which are formed by certain sea algae can be the cause of tingling sensation around the area of the mouth, and can also cause nausea, with muscle paralysis or even death due to respiratory failure. Neurological disorders like multiple sclerosis, trigeminal neuralgia are other causes of tingling in the mouth and lip region.
Some studies have indicated that twitching of a kind is related to stress be it work related stress, dysfunctional family relations or any other kind of stress. So lips trembling or vibrating could be a sign of stress. Taking up some relaxing activity like yoga or aerobics can help you de stress as does walking or listening to music. It could also be a sign of intense emotion. Other theories are that twitching could be a sign of magnesium deficiency. Magnesium is used to help the muscles in the body to relax. Having a hot bath with Epsom salts dissolved in it helps relaxation. It further helps in drawing out the toxins from one’s body. At times it could be an indication of a neurological disorder. To confirm this doctors run various tests.
