Lip filler occluded treated with hyaluronidase instantly but still in pain? Is this bruising or necrosis? (Photos)

Had 1ml filler done Weds bottom lip occluded, hyalase was used instantly and colour returned. 2 days after woke up in excessive agony across the chin area, returned to clinic and have been given antibiotics and steroid course. Still concerned this is necrosis? I have small white pimples developing. Also my concern was that I have a chin implant inserted 6 years ago, could the hyalase have effected this? The surgeon thinks I have either had a reaction to the hyalase or too much has been inserted.
