Extraordinary pain with hyaluronidase? I had too much Voluma in my cheeks about a month ago.

Because I am abroad for awhile, I went to a reputable foreign doctor for hyaluronidase. I've had Vitrase and Hylenex before w/ minimal pain, but these injections were SO painful. They burned horribly. 2 hours later, the areas are warm and tingly. Is there a difference between pure hyaluronidase and Vitrase/Hylenex? What might account for the difference in my experiences w/ hyaluronidase. I'm concerned I've done serious damage.
