I took hold of a branch and felt a stabbing pain in my left hand between my ring and middle fingers. Searching through the leaves, I discovered the furry caterpillar.

A few minutes more and the pain had reached my armpit and shoulder. At that point, the progression stopped and I had no further symptoms except the pain which kept me from sleeping all night.
