There are a couple different sets of pressure point to relieve shoulder pain. It all depends on the location of the pain and differentiation of the diagnosis. For example, LI 4, LI 10, SI 6, Lung 9, the best solution is to talk to your practitioner.

You may press on the following points of the affected side of the shoulder with gentle movement: SJ-4 (on the transverse crease of the dorsum of wrist, in the depression lateral to the tendon of m. extensor digitorum communis) and SI-6 (Dorsal to the head of ulna. When the palm faces the chest, the point in in the boney cleft on the radial side of styloid process of the ulna). Or Auricular points: Axilla - on the scapha above shoulder pain point, and shoulder pain - on the scapha superior and medial to shoulder joint point.
Gb21 generally. But where is the exact location, anterior, posterior, lateral?
Hope that helps.
All the best.
