Continued Numbness from Restylane Injection?

First and I hate to say this, but overseas, you don't know if what you really had was Restylane, so hyaluronidase might not be the right thing to use anyway. I've had people come in from foreign countries having had 'Restylane' or 'Juvederm' and what they actually had was who knows what...silicone, Crisco, glue, and many other fun things. So first, let's hope it really is Restylane.... Sometimes a nerve can be affected with an injection, though it does usually return to feeling with time. Usually this happens more on the scalp when doing surgeries, and the nerves do reconnect and feeling comes back. I don't know if this could have happened to you, but I suppose if a nerve was somehow affected with the injection, it could have created a loss of feeling for you in that area. The other, bad option, is that you are experiencing necrosis, which means that an artery has been affected by the filler and is blocked, in which case it can affect blood flow to that area, which then can affect the feeling you have there. If you've consulted a plastic surgeon and neurologist, I'd hope they'd have checked for this, which would look like a spreading white/pink area with areas of increasing blackness. If no one has looked at this in person, please have it evaluated again for possible necrosis.
