Is this normal? What should I do?

Thank you for your question. Injections of any substance into the skin can give bruising. Other than unpleasant visually, there is nothing to be concerned about. It usually resolved in 1-2 weeks. The "blisters" are unusual. You should see a board certified oculoplastic surgeon to evaluate your problem. Good luck. 

Dear jaraba1,The discomfort you are feeling is normal. It may take up 2-4 weeks to the swelling you have experienced to subside. I suggest making an appointment with the doctor for a month after surgery so that you can discuss your concerns and track your progress at this point. Remember to consult a board certified facial plastic surgeon to ensure you receive some of the highest-quality care. Sincerely,Ross A. Clevens, MD, FACSClevens Face and Body Specialists

Bruising is quite uncommon with Botox injections. If a bruise starts spreading after a few daysAnd is accompanied by blisters and there is a risk of having shingles.  This needs to be examined by a physician to determine if the patient needs to go on antiviral medication.  There is also risk of bacterial infection which would require antibiotics.  Treatment should not be delayed as shingles can leave behind permanent scarring and certain areas.RegardsDr. J
