Weak Shoulder

How Chinese medicine differentiates a weak, unstable shoulder — distinct from Shoulder Stiffness and Frozen Shoulder already covered, where the complaint is weakness rather than restricted range — the five patterns you'll actually meet in practice, and the points for each. Acupuncture only — no herbs.

This page is educational, for practitioners and students — it is not a diagnostic tool and does not replace a proper in-person assessment. Sudden weakness, especially one-sided or with numbness, needs prompt medical evaluation to rule out a neurological cause before assuming a simple pattern.

General Acupuncture Points

Acupuncture points traditionally used for a weak shoulder — 10 key points, used across the patterns below rather than tied to just one.

The Five Patterns

↑ reinforcing ↓ reducing ⊥ even method.

1. Qi and Blood Deficiency

Clinical manifestations: Dull ache with a heavy, weak, easily-fatigued shoulder, worse with use and better with rest, pale complexion, general fatigue, poor appetite.

Tongue: Pale, thin, teeth-marked, thin white coating. Pulse: Fine and weak, especially at both Guan positions.

Treatment principle: Tonify Qi and Blood to restore strength to the sinews and channels.

ST-36 ↑ SP-6 ↑ L.I.-15 ⊥

Note: moxa applicable throughout. This is the generic Qi-and-Blood-deficiency picture, already confirmed absent as a standalone slide on this site many times over — no pattern link is given; points still link fine individually.

2. Blood Stagnation View full pattern →

Clinical manifestations: Fixed, aching weakness that follows an old injury, worse with pressure or cold, stiffness alongside the weakness, occasional stabbing sensation.

Tongue: Purple or dusky body with stasis spots. Pulse: Choppy or wiry.

Treatment principle: Invigorate Blood, dispel stasis, open the local channels.

G.B.-21 ⊥ BL-17 ↓ LR-3 ↓

Note: no moxa. Direct match with this site's own Liver-Blood-stasis slide via the well-established stasis-spot-tongue marker.

3. Painful Obstruction With Wind-Cold-Damp

Clinical manifestations: Weakness with heaviness and stiffness, worsens in cold/damp weather, aversion to cold and wind, numbness, no local heat.

Tongue: Pale, swollen, white greasy coating. Pulse: Wiry/tight or soggy/slow.

Treatment principle: Dispel Wind-Cold-Damp, unblock the channels, restore circulation.

G.B.-20 ↓ L.I.-15 ⊥ ST-38 ⊥

Note: no moxa unless Cold clearly dominates. This is the generic Wind-Cold-Damp Bi-syndrome picture, already confirmed absent as a standalone slide on this site many times over — no pattern link is given; points still link fine individually.

4. Damp-Heat in the Liver Channel View full pattern →

Clinical manifestations: Shoulder weakness with a heavy, sluggish sensation, alongside genital itching or discharge, bitter taste, scanty dark urine, irritability.

Tongue: Red with a yellow greasy coating, especially at the sides. Pulse: Wiry and rapid, or wiry-slippery.

Treatment principle: Clear Damp-Heat from the Liver channel, restoring free flow so strength can return.

LR-3 ↓ G.B.-34 ↓ ST-40 ↓

Note: no moxa. Genuine match with this site's own Damp-Heat-in-the-Liver-channel slide — the source explicitly names genital itching/discharge alongside the shoulder complaint, satisfying the genital-specific-slide rule for this deck's #5/#6 pair.

5. Phlegm in the Channels

Clinical manifestations: Numb, heavy weakness with a sensation of fullness, possible small soft lumps along the shoulder, worse in damp weather, mental heaviness.

Tongue: Pale or normal, swollen, white greasy or slippery coating. Pulse: Slippery.

Treatment principle: Resolve Phlegm and dissipate obstruction from the channels.

ST-40 ↓ L.I.-15 ⊥ G.B.-21 ⊥

Note: no moxa. This site has no organ-nonspecific Phlegm-in-the-channels slide, a gap already confirmed absent many times over — no pattern link is given; points still link fine individually.
