Did I get optic nerve damage from a Restylane injection?

Two days ago I got Restylane lyft in Beverly Hills. The doctor is well-reviewed on RealSelf and specializes in eye areas. He put it in the area between my temple and eye, and just under my eyebrow. While he was injecting, I felt a sudden, strange feeling, like the hairs on my head were pulled. Not painful, but strange. He said he hit a nerve and this is normal. Since then, if I touch a certain spot on my brow, I feel the nerve ending somewhere else. Is there permanent damage?
