How would you describe the occurence of cold sensation? Is it like someone spraying cold water on your face? Is there numbness involved? Is there a tingling sensation?
Facial coldness can be caused by several things, including environmental factors, neurological disease, diabetes, alcohol-related neuropathy, hypothermia and facial injury. The concomitant finding of lip twitching might point to a neurological cause as very possible.
Symptoms of tingling, decreased or heightened sensation, or numbness is usually a symptom related to a damaged sensory nerve, either as a result of nerve entrapment or direct pressure to the nerve or the spinal attachment of that nerve, or a disease condition affecting the nerves such as neuropathies, multiple sclerosis, diabetes, etc.
While the symptoms you are experiencing right now are, at the most, just annoying, they can sometimes indicate a serious medical condition requiring prompt medical diagnosis by a professional. If you are concerned about your condition, consult a neurologist.
