Thank you for your question caroline hewson. I am sorry to hear about your situation. Botox is a purified protein used to address wrinkles associated with facial expression. Swelling associated with injections typically lasts up to two weeks, but sometimes longer. If too much filler is placed in a certain area it can be dissolved if it is a hyaluronic acid filler such as Juvederm, Voluma, Volbella, Restylane, or Belotero. Please follow up with your doctor for specific recommendations. Good luck!
