I had a second round of hyaluronidase placed on each cheeks due to imflammation , overfill of juvederm, also 8 units of botox just on my forehead same day. A week later my left cheek is swollen, very painful, numb and my upper left lip will not move. (Looks like I had a stroke). I have had botox for the pass 5 yrs no issues. The first round of hyaluronidase didn't to this.
