3 days ago I injected myself with Juvederm. What should I do? Where I can get help?

it seems like you made a big mistake and need to see a cosmetic dermatologist who can evaluate you for any complications.  Best, Dr. Emer.

Thank you for sharing your experience and it is imperative that you present to your local ER to be appropriately evaluated by a healthcare professional in addition to a referral with a plastic surgery or dermatology specialist for care.  

This is obviously a very poor idea. It is unknown exactly what was injected. You need to go to the emergency room to get treated. Antibiotics, steroid, surgical drainage are all possibilities. You need a thorough evaluation by an ENT or Plastic Surgeon.

Respectfully, you do not really know WHAT you injected into yourself. (There is a multi-billion dollar counterfeit market much of it from China dealing with fake medicine which are harming millions. The sale and importation of "fillers" from overseas is strictly controlled and doctors who use such fillers are subject to jail time). Second, you don;t know if the "filler" was really sterile (You could be having an infection). Lastly, you don;t know WHERE or into what structures you injected this product.Your only recourse is to go to a real ER or a University based ER where a doctor in the know may evaluate you and suggest treatment. The longer you wait, the worse and more irreversible the process may become.Do NOT throw the packaging and syringe out. Similarly, save all the information and dealings with the person and source of the "filler" you bought since this may be needed in the future in any investigation which gets launched Or it may be needed by any lawyer you may need to hire to recoup money for your future medical care.

You will need to be examined by a plastic surgeon or dermatologist that can evaluate you and help you.Best wishes,Dr. Denkler
