Weeks after botox I have swollen eyelids & skin at corners of my eyes is rough & itchy. What can I use to heal it?

I had botox on my forehead and now (weeks later) have droopy, swollen eyelids and the skin near the corners of my eyes (and under my eyes) is rough, red, and a itchy. I assume I am having an allergic reaction. What (other than time!) can I put on my face now to make it feel better or to speed the botox out of my system?
