Twitching on the left side of a person's face can be anything from an isolated muscle spasm to a very serious medical condition. Twitching usually occurs when an individual is extremely stressed out. These symptoms are also known to be a result of not getting enough sleep. This is only one of many reasons why it is recommended that adults get at least eight hours of uninterrupted sleep each
. night. Twitching on the left side of a person's face may also come as a result of a malignant tumor. The gravity of this condition is immense, which is why people who experience these symptoms should contact a medical professional as soon as possible. This is also sometimes the result of benign fasciculation syndrome. This is a very rare disorder and the only symptom is twitching or light muscle spams. Although it does not present any serious adverse health effects, it can still prove very unnerving or annoying to many individuals. Bells palsy can also induce this kind of twitching as a result of nerve damage. This can lead to muscular paralysis or pain in various areas of the face or ears. Sometimes this kind of twitching can be the result of a body part falling asleep. The nerves are desensitized in this situation and may twitch for a short period of time afterwards. This is only temporary, and not a great cause for concern.Twitching on the left side of the face can also propagate as a reaction to various medications. Certain drugs can alter the speed at which signals are transmitted between neurons in the body. This type of side effect is not necessarily serious enough to warrant attention, but it is always good to have the advice of a doctor or general physician in terms of side effects to new medications.
