Juvederm Delayed Hypersensitivity Reaction Vs. Infection Vs. Sinus Infection - New York, NY

I've been seeing the same NP for Juvederm and Botox for a few years. Recently I had Juvederm to my nasolabial folds, some Botox to the frown lines above nose, and sides of the eyes. I went to see my primary a week ago when I woke up with a swollen left eyelid, conjunctivitis, and symptoms of a sinus infection (nothing new for me, I tend to get them). I was febrile 100.8. I started Biaxin XL 1000mg once a day 6 days ago. The eye issue resolved quickly. The left cheek was swollen just anterior to where I had the injection (I don't know if it was at the onset of the other issues, I didn't notice). I went back to see him the following Thursday when the cheek swelling did abate after 3 days of antibiotics (we assumed it was r/t the maxillary sinus issue) and still had a low-grade temperature (99.5). He said I should see a derm as it may be hypersensitivity or infection. I saw my derm that afternoon. The derm felt my skin for two seconds and declared it was a strep infection, and wanted to send me to an infectious disease MD as I have many allergies to antibiotics and he felt the Biaxin wasn't working. I opted not to go, as I never had any pain or unusual skin appearance (other than redness). I still have some edema and erythema to the left cheek, and now the right cheek is a bit pink. I also have a history of rosacea, which has been flaring a bit as of late due to stress. It nowf eels like a vasodilation response happening all the time (like blushing) to both cheeks, but mostly the left. I no longer have a temperature, but can't figure out what is going on. I don't see it as being an infection as I don't really have pain with palpation to the area, it's just uncomfortable due to pressure. I don't want to go through another MD only to have him tell me the same things. Biaxin should cover an infection in the cheek if I had one. I put in a call to the NP who injected me and left a detailed message with her secretary, and she never called me back, never mind seeing me to assess the situation. I have not had hypersensitivity to Juvederm before, however, I have a history of allergies. The other thing worth mentioning, since I have seen information about "fake" Juvederm, is I did not see her using a pre-packaged Juvederm syringe while doing the injections. I know it comes pre-packaged, so I am not sure why it would not be in that syringe, unless she thought she didn't need the whole syringe......but she charged me for it. I really don't think it is an infection, even though the symptoms of infection of slightly warm to touch, slightly edematous, and somewhat reddened are present, as I would expect pain and and a much worse appearance. My take is it is hypersensitivity (especially if a substitute filler was used) or a part of the sinus issue. Any input is appreciated!!
