Figure 3. Complete spontaneous resolution of running-associated post ambulatory swollen hands (POTASH).

All the hand and digital swelling associated with POTASH completely resolved spontaneously within two hours after the patient stopped running. There is no edema in the previously swollen dorsal left (A) and right (B) hands (red ovals); skin lines, superficial blood vessels, and tendons can be seen. Previous swelling of the dorsal thumbs (white ovals) and fingers (blue ovals) is gone (A and B). Dorsal (A) and palmar (C) views of the fourth finger do not show any swelling proximal or distal to the gold ring (blue oval). The creases on the palms (red ovals) are deeper and more prominent (C and D); there is no swelling of the ventral thumbs (white ovals) and fingers (blue ovals) (C and D). Photographs of the hands were taken 24 hours after the patient stopped running.
