Hi,
Thank you for posting your query.
The common causes of spontaneous swelling of lips is
allergy or insect bite.
The
twitch in eyelids is unrelated to the
lip swelling and is usually caused due to strain/
stress.
Please get examined by a general physician for evaluation and treatment.
There is no immediate cause for concern.
Please get back if you require any additional information.
Best wishes,
