I am in the midst of sorting new soft-cover children’s books for the 340 or so students who will receive five each before they leave school for the summer. Each book we give is stamped with the words, “This book is a gift from” the church’s name and address. So I have been carefully stamping at least 1700 (it is good to have extras, just in case) books, as well as sorting them by grade level, and packing them into boxes for transport between my home where I have done the accounting, and the place where they will be put into bags for the students by volunteers.
I have developed a pain in a muscle — or is it a tendon? — in my upper arm that is rather remarkable in its intensity, so much so that I would like to know the name of the muscle, or tendon, so that I can speak gentle soothing words to it as I offer it hot tea and a compress. The stamp is the culprit. It is a fussy self-inking type that requires the page to be just so, the surface underneath perfectly flat, a rhythm of movement that is slow and deliberate with a particular amount of firm pressure. My arm hurts just thinking about it. I have a few hundred more books to go. Maybe I would be better off hand-writing the rest of them. Or maybe not.
So, let’s self-diagnose. Lateral head of the triceps brachii?
