Extremely Swollen Red Sore After Botox? (photo)

Based on the photo's shown, the swelling around the eyes is noted -  it's still very difficult to determine what may or may not be going on but discussing this at length with your provider and their suggestions for treatment going forward are a good place to start.

This is more than likely NOT from the Botox product but from some ingredient that it was reconstituted with. For whatever reason, be it allergic or infectious, your body is reacting strongly to this. I recommend speaking with your physician to see what product you may have been allergic to, and seeing an allergist. If you don't come up with anything there, I'd recommend seeing a new physician. Perhaps you received an improperly mixed or stored product. If the symptoms don't improve or get worse, please see your GP or ER. In the meantime, try cool soaks and Benadryl. 

I have to agree with the prior physicians.  Either you got some substitute for Botox or you are allergic to the preservative in the saline used to mix up the Botox.  It would seem if you had an allergy that it would've manifested itself in the past.  Most likely you didn't get BOTOX.  This is a competitive market and some practices try to cut costs by not buying from Allergan.  There is potential for counterfeit products.  Buying from Allergan is the only way you know what you are getting from a physician standpoint, and the only way to be assured it's been handled correctly.  Botox is temperature sensitive, so if it gets hot, there is the possibility it loses it's strength.  I believe that buying from anyone other than Allergan is not legal.  Check BOTOXCosmetic's website to see if your doctor is listed.  If he/she is not, they are not buying from Allergan.  If they are, it still doesn't mean that they buy all their Botox from Allergan - they might be buying some from them, and the rest from someone else.  It's best to go to someone you can trust and not necessarily the lowest price.
