^‡The assessment of hand swelling included difficulty to: (1) make a fist, or (2) remove rings, or (3) remove a watch or wrist band.

^§A description of the fingers of hikers and walkers starting to swell like sausages while they were ambulating on the trail was provided; however, the author did not discuss the fist sign in his article.

^‖The acronym POTASH is derived from post ambulatory swollen hands. POT are the first, second, and fourth letters of the word post. A, S, and H are the first letters of the words ambulatory, swollen, and hands.
