Involuntary movements of the eye and lip. i have this small contractions of the lip and a small movement in the eye for about a month. what can it be.

Twitches: Small twitches at the corner of the mouth or of the eyelids occasionally occur when we are stressed (tired, emotionally strained, etc.). Although they are annoying, they usually disappear within a few weeks. Rest, cool compresses, identifying and decreasing the stressor can all help. If the twitches become severe, painful or so not resolve, see your doctor.

Hemifacial spasm: If the eye is forcibly closing with a contraction of the same side of the face and an upward moving of the lip then this may be hemifacial spasm. This is usually a benign condition but evaluation by an eyemd is needed to rule out associated eye or neurological pathology.
