Antibiotics and Prednisone for Radiesse Problems

I had Radiesse injected on my nasolabial folds four days ago. On the second day, I had a lot of swelling on the left side of my face. On the third day, my upper lip and left side of nose were extremely swollen and smile was a bit crooked. I was in a lot of pain. I called my doctor who had me come in within a few hours. She ruled out any artery or blood vessel issues, but believed I had an infection and adverse reaction at the sites where Novacaine and Radiesse were injected. She called in another doctor within the practice to review/confirm her opinions. They agreed that I needed to take an antibiotic, prednisone (oral steriod), vicodin (as needed for sleep/pain), antihistamine (which I already take) and another medication for herpes simplex. This last one was because I had unexpected sores on the underside of my upper lip. On the fourth day, I developed small postules on left hand side near nose and nasolabial fold. They got better (but not gone) in the afternoon. I spoke with the doctor and she believes it's an infection that will be resolved with the antibiotic that I'm now taking. How long do you think I should take the antibiotics and Prednisone?
