Are there doctors who will be willing to dissolve my Juvederm even if they didn't inject it?

As you point out, the quality of filler injection results is physician dependent.  Seek experienced board-certified specialists in plastic surgery, otolaryngology (ENT) or ophthalmology, who personally perform or have experienced, well supervised nurses or nurse practitioners.  Seek a professional medical environment.  In you area, I suspect there are many choices of experienced physicians who can and will evaluate you and offer treatment with hyaluronidase if they feel it can help you.  Then you can develop a relationship with an office that can help maintain you filler and other needs.For a plastic surgeon, check the American Society of Aesthetic Plastic Surgeons (ASAPS) website.  Their new slogan is "We Are Aesthetics."

Chicago has many skilled and highly competent plastic surgeons. Surely there is a doctor there who will treat you with hyaluronidase but you will most certainly have to pay for their skills/expertise, time, and taking on of liability of another healthcare provider's injection. You may want to consider Dr. Julius Few. He is meticulous, competent, and highly experienced in oculoplastic surgery and fillers. Get in sooner than later in case you need more than one treatment before your trip. Best of luck!
