I got a terrible case of it hanging stands a month ago. Same thing, vine growing up the tree and tore it off. My face swelled up so bad I couldn't see and my arm still has the scars. The Zanfel didn't even faze it, although it usually works. Went to the doctor and he asked who beat me up. Got the steroid shot and pills and was better in a week. Go to the doctor before it gets real bad.
