This usually needs to be combined with the patient’s medical history.
If the patient has temporary tingling of the lips and the skin of the lips is accompanied by redness or a rash, this may be caused by skin contact with an allergen.
If the patient works in a special job and is exposed to or exposed to a special environment for a long period of time, this may be due to a mineral deficiency in the body.
If the patient has other symptoms such as recurrent episodes of transient, paroxysmal, sharp electric shock-like, knife-like or tearing pain in addition to the symptoms of numbness in the lips, it may be related to damage or compression of the trigeminal nerve, for example.
