It is important for you to know if it was a true allergy to hyaluronidase or just excessive bruising.
You mention the word -black along with the swelling hours after hyaluronidase injection. Please tell me if you got a lot of bruising. If you did then it is possible that what you have described is prolonged lower lid edema after excessive ecchymoses (bruising).
If you can describe the situation in more detail with some photos from after the hyaluronidase injection (same day) that would be helpful.
At this point, watchful waiting and letting the eyelids heal is the best thing you can do.
Please keep us posted.
