Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain quivering of lips along with numbness is generally seems to be due to Apthous Ulcers or Canker Sores.. Other causes that can also commonly cause quiver of lips and numbness are Vitamin B12 and calcium deficiency, potassium deficiency, 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 first of all consult a General Physician and get evaluated and a thorough clinical evaluation can help in diagnosis.. 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.. Apply Antibiotic Ointment over the Ulcer and do cool compresses.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
