Thanks for posting your query at DoctorSpring.com
I can understand your concern.
I would recommend that you take Tab. Tylenol for the pain.
I would like to know if there was any filler injected in that area. Also whether a numbing cream was applied on that area before the filler was done? Which filler was used for the lips?
I am suspecting a reaction to the numbing cream. Hence I would like to know the answers to my queries.
