Severe Neurological Symptoms After Juvederm, What Can I Do?

Juvederm injections would be highly unlikely to result in neurological symptoms.  The substance is totally natural and doesn't affect the nerves.  There are possible side effects that can occur such as bruising, and even skin problems such as skin loss in an extreme situation, but not what you are describing.  Seeing an additional physician is mandatory, and further testing will be required so a diagnosis can be indentified.  Make an appointent immediately to continue your evaluation, but these symptoms would not due to the Juvederm.

Neurological symptoms occuring after Juvederm are essentially impossible. I have training in two subspecialties, neuro-ophthalmology and oculoplastic surgery. The neurological symptoms that you may be having are generally secondary to a problem that is occuring in the brain or spinal cord.  Juvederm is injected into the skin. Additionally, the hyaluronidase which was injected dissolves it. 

There is something that occurs in medicine where patients prescribe a medical illness or problem secondary to what we call "a sentinel event". The best example was when I was an intern I had a patient who was playing catch with his son and the football hit him in the chest by accident. Everything was fine but two weeks later he started coughing blood and after several tests it was determined he had lung cancer. The patient however convinced without a doubt that the cause of the lung cancer was the football that hit him in the chest. After all, he was fine before the football hit him and it was only two weeks later when he started coughing blood.  It is quite well known that a football hitting someone in the chest doesn't cause lung cancer but the patient was convinced and no amount of explanation etc.. would change his mind. 

This phenomenon is seen in all aspects of medicine and even in plastic surgery. Patients will get a facelift and subsequently develop breast cancer 6 months later and believe it is linked. Or patients will get the flu after botox and believe the botox caused the flu etc.. 

The problem you are having sounds neurological which is not linked to Juvederm which not only is only injected into your skin, does not get into the blood stream and also not into your brain or spinal cord. It is most likely a large coincidence. 

It's true that if a dermal filler is injected into the glabella, it can potentially have serious side effects, but not the ones you are describing.

If Juvederm or any other filler is injected into the glabella, it may compress or even more rarely be injected into the superficial blood vessels and result in skin tissue necrosis due to the interruption of blood supply.  That would not account for the weight loss, headaches, memory loss and blurry vision.

If there were tissue necrosis, there may be some burning associated with it, but the signs of tissue breakdown and ulcer formation would also be there.

I urge you to seek medical care as soon as possible to determine the cause of your symptoms.
