Could hylenex be causing ringing in the ear and headaches?

After getting 30 units concentrated hylenex on radix of nose to dissolve Juvederm ultra approx 3 days later had ringing in one ear and headache the ringing is still present in right ear? More injections were done on the right side as more filler was in area. Pls advise I'd love to hear possible scenarios for this. Has it ever happened before. Have you reversed fillers in this area with no problems. I had no bruising or any other side effects after. Could it travel to Eustachian tube.
