Left temple down to side of face still tingles when rubbed. Right temple tingles less and that eyebrow recovered,but left frontalis muscle still paralyzed and 1" lower w/o Botox. Is this common this late? A sign that paralyzed left eyebrow could recover? If braided suture DID fail on paralyzed side (as doc thinks)would this cut the frontalis or did it just get injured in surgery? Does it need removal? How often does this happen? I am so worried it will never recover. My eyes have no expression.
