Radiesse allergic reaction? Can anyone advise me?

This would be a very unusual reaction. I recommend seeing an allergist right away. In the interim you might consider taking Zyrtec or Claritin during the day and Benedryl at night - ask your primary care doctor for dosage. 

A true allergic reaction is rare but anything is possible and you should, of course, address this with your own plastic surgeon.  For an allergic reaction, and particularly one that, like this one, appears to be systemic, a discussion with your internist is of paramount importance.  You may benefit from a course of steroids and, of course, you have to be sure that this is an allergy to the Radiesse - that's what you're assuming it is and you may be right - but you can't make that assessment on your own.I hope that this helps and good luck,Dr. Alan EnglerMember of RealSelf100
