That's too bad. They can be really awful. I had mine in July 2019, on the left side of my forehead and face down onto my eyelid. Fortunately no lesions on my eye itself as I understand that is even possible, but my left eye was swelled completely shut for about a week. I don't know what would be worse, on the torso and back or on the face, but at least I could lay on my back to sleep without any pain. It left a big light colored lightning bold looking kind of scar right in the middle of my forehead that hasn't gone away yet.
I hope you get over them quickly.
Regards,
Dave
