Hi, I have a pulsation to the left of my mouth that developed about 6 months ago out of nowhere. Its about the size of a pea and pulsates with my heart beat. I looked at some anatomy drawings of the vascular system traveling thoughout the face and it seems that it could be where an artery exists. What can I do to get rid of this? Its driving me crazy. Thank you!!
Hi, welcome to Chat Doctor forum.  It appears to be the aneurysm of the facial artery, which usually present there. Or there could be some infection in the nearby tissues of facial artery.  I advise you to consult a vascular surgeon for diagnosis and treatment. You may need to have color Doppler for confirmation.  Wishing for a good health. Thank you.
