Crooked lips after facial contouring

It's been almost a month since I had the 3-step facial contouring procedure, and most of my sensation and everything has returned (I haven't had any problems with sensation since the surgery), but when I pronounce "ee," my lower right lip in particular doesn't move, so my pronunciation is harsh and my lips are crooked. I asked the surgeon and he said that it's because the left and right sides recover at different speeds, and that my facial motor nerves weren't damaged, and that it would be okay in about a month. He told me to relax and practice my pronunciation and injected botox into my left jaw. The surgeon who performed my procedure is really good and trustworthy, so I'm just waiting and thinking that time will heal, but I can't help but feel a little anxious ㅜㅜ If there's anyone who had similar symptoms to me, please tell me what it was like and if it's okay now. Please ㅜ
