Curious about lip spasms/twitching. the right side of my lower lip seems to pull/spasm at times. it doesnt do it at rest. only if im talking or laughing, and even then it only happens sporadically. what are some possible causes?

Possible causes are anxiety & dehydration consider limiting sodas & coffee. Eat a well balanced diet and sleep 7-9 hours. If symptoms become more than sporadic, see your primary care for a possible referral to a neurologist. Your lips are innervated by a large, facial cranial nerve. Keeping a log will help your doctor as well as any history of trauma. Your dentist can do a basic cranial nerve exam
