Botox 90 days ago caused cheek ptosis - please advise (Photos)

90 days ago had Botox on crows feet by facial PS. 3-5 days later cheeks felt tight and could barely smile. Right cheek has seemed to get much better but there is a deep indent (shelf) on left cheek when I smile. C bone area looks very flat at rest. Worsen of nasolabial fold too. Got second opinion from PS- she said cheek ptosis and zygomaticus was affected. 3-6 months. Do you agree with this? I'm so distressed. Could there be permanent paralysis? Cheek isn't lifting past shelf.
