Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain lip twitching also known as Lip Quiver can occur in conditions like
Vitamin B12 and
calcium deficiency, potassium and calcium deficiency,side effects of medications, traumatic injury or inflammation of
facial nerve that supplies muscles of face,anxiety and panic attacks,
nerve inflammation and infection caused by viruses etc..
I would suggest you to consult a Neurophysician and get evaluated and you can be advised to get investigations done like MRI, CT Scan, Nerve conduction studies, Electromyogram etc to rule out the exact cause of the problem and treat you accordingly..
You can be advised to take multivitamins along with calcium and potassium supplements..
You can do warm compresses over the lips.
You can also do breathing exercises along with
meditation to keep stress minimal..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
