I had 1cc Restalyne injected for tear troughs. Questions about possible complications and how long mild pain should last.

Hi all! I had 1cc total of Restalyne (.5cc under each eye) to help improve the appearance of dark eye circles. I had my Restalyne done by an experienced injector who is also an MD. A day after my procedure, I got a mild tingling pain in my eyes. I occasionally get this mild pain (its only day 3), but it is enough to give me a ton of anxiety. My doctor tells me that the risk of blindness or anything going wrong is 0%, as it has already been 3 days after my procedure and my vision is unchanged.
