Spasm means "uncontrolled muscle contraction". The term blepharospasm ['blef-a-ro-spaz-m] can be applied to any abnormal blinking or eyelid tic or twitch resulting from any cause, ranging from dry eyes to Tourette's syndrome to tardive dyskinesia. The blepharospasm referred to here is officially called benign essential blepharospasm (BEB) to ...
Benign fasciculation syndrome (BFS) is characterized by fasciculation (twitching) of voluntary muscles in the body. [1] The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, hands, fingers, legs, and feet. The tongue can also be affected. The twitching may be occasional to continuous. [2]
Treatment can change the way a patient looks, talks, eats, chews, swallows or breathes, it adds. Only about 1,200 people are diagnosed each year with adenoid cystic carcinoma, the type of cancer ...
Blepharospasm is often associated with dry eyes, but the causal mechanism is still not clear. [16] [8] Research in New York and Italy suggests that increased blinking (which may be triggered by dry eyes) leads to blepharospasm. [24] [25] A case control study in China found that blepharospasm aggravated dry eyes. [26]
When your right eye is twitching, it could be due to stress, fatigue or even dry eyes. Unless there's an underlying medical condition, eye twitches tend to come and go like the wind.
“Any type of right-side chest pain that feels like a sharp, severe, tearing sensation that radiates to your back could indicate an aorta dissection, which is a tear in your aorta,” says Dr ...
Sometimes there is flushing on the affected side of the face due to dilation of blood vessels under the skin. The pupil's light reflex is maintained as this is controlled via the parasympathetic nervous system. [citation needed] In children, Horner's syndrome sometimes leads to heterochromia, a difference in eye color between the two eyes. [3]
Hemifacial spasm (HFS) is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions on one side (hemi-) of the face (-facial). [1] The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it separates into five main branches.
