I had Juvederm injected in my cheeks (2 syringes). After, my ears started presenting with a slight infection, aching gums/teeth & pain in front of my ears. 6 months later I am experiencing sinus issues which have made my frontal sinus swell out. The doctor told me it appears I have a blockage in my sinus canal from my nose up to my ears. I read this - " FDA Warns of Complications From Facial Fillers when injections accidentally enter blood vessels, blockages and damage can occur". Is this true?
