The extensor digiti minimi originates from the lateral epicondyle of the humerus, or the outer edge of the elbow if the palm is facing up, in the anatomical position. It runs along the back of the back of the arm to the wrist and past the wrist to the proximal phalanx V, or the bone between the genital knuckle and first bend of the finger of the little finger.
RX is always ice 30 minutes 2 – 3 x a day on the painful area. Take anti-inflammatory meds, stretch, and tape the shin and arch before any physical activity.
Becaus these muscles extend the wrist, it becomes painful to extend the wrist and us it in actions that require resistance.
