Abductor digiti minimi: ulna (medial) side of base of proximal phalanx of little finger.
Dorsal interossei: abduct fingers away from middle nger.
Assist in flexion of fingers at metacarpophalangeal joints.
Antagonist: palmar interossei. Lumbricales: extend interphalangeal joints and simultaneously flex metacarpophalangeal joints of fingers.

Other dorsal interossei: referred pain to specific associated finger. Lumbricales: pattern is similar to interossei.
Abductor digiti minimi: pain in dorsum of little finger.
Finger pain/stiffness, pain when pinching/gripping, associated with Heberden’s node(s) - (e.g. in professional musicians, especially pianists), “arthritic” finger pain, also seen in artists/sculptors, Bouchard’s nodes (middle knuckles).
Repetitive grasping, occupational, computer mouse, post wrist fracture and/or splinting, grasping, carrying shopping, typing, massaging, fine handiwork (e.g. writing, sewing, knitting, artwork, painting, airbrushing), playing musical instruments (e.g. piano, violin, guitar), sports (e.g. golf, archery, fencing).
Cervical radiculopathy. Ulnar neuritis. Thoracic outlet syndrome. Digital nerve entrapment. Articular dysfunction.
Intrinsic thumb muscles, scalenes, latissimus dorsi, long finger flexors/ extensors, pectoralis major, lateral/ medial head triceps brachii.
Self-massage/pressure techniques can be really helpful. Simply locating trigger points and pressing with other thumb can be enough; remember to hold trigger point until it softens.
Alternatively, a range of pressure devices can be used, or even a pencil with a rubber (never use the "sharp" end!).
Take a break from repetitive activities and stretch out. Stretching and exercising. Examine work postures/ergonomics. Explore sporting activities (e.g. grip in golf). Use of ergonomic pens/cutlery.
