Can’t Lift Arm, Worse Pain at Night – Is It Frozen Shoulder?
We treat not just inflammation but stiffened movement issues.
Starts with stiffness, then gradually arm won’t lift. Pain worsens when dressing or washing hair, and sleeping on the affected side becomes difficult at night.
3 Key Points This Page Explains
- What symptoms indicate frozen shoulder
- Why it keeps stiffening and hurting – the mechanism
- How to treat it to prevent re-stiffening
These Symptoms May Indicate Frozen Shoulder
- Can’t lift arm – Hard to reach overhead or get items from high places.
- Worse pain at night – Okay during day but throbbing at night, worse when lying on affected side.
- Difficult to dress/undress – Hard to put arm in sleeve or reach behind for bra clasp.
- Clearly different from other side – Comparing both shoulders shows affected side lifts much less.
- Progressive stiffening – What was slightly uncomfortable becomes worse over weeks and months with less movement.
Why Does Shoulder Stiffen?
Frozen shoulder (adhesive capsulitis) is a condition where the capsule surrounding shoulder joint thickens and stiffens.
Various causes exist, but the common factor is persistent state of ‘reduced movement and decreased circulation’.
- Prolonged same posture – Surrounding tissues gradually stiffen when shoulder isn’t used.
- Post-injury sequelae – Not moving shoulder due to pain after injury leads to stiffening.
- Poor circulation – Blood flow drops and fascia sticks together, blocking subtle movements.
- Diabetes, thyroid disease – Metabolic problems increase frozen shoulder incidence.
3 Stages of Frozen Shoulder
Stage 1 (Freezing)
Pain starts and movement gradually decreases. 2-9 months.
Stage 2 (Frozen)
Pain reduces but stiffness persists. 4-12 months.
Stage 3 (Thawing)
Gradually loosens. 5-24 months or more.
Natural course without active treatment can take 1-3 years.
Simple Self-Check at Home
- Lift both arms facing wall
Stand facing wall and slowly lift both arms simultaneously. Does one arm lift less or stop midway? - Reach behind back
Reach both hands behind back toward upper back. Does affected hand stop at lower position? - Lift arms to side
Lift both arms out to sides. Does pain worsen between 60-120 degrees? - Daily activity check
Any particular difficulty with washing hair, dressing, using back pocket?
※ If pain feels severe, stop and don’t force it. Forcing movement can cause more damage.

Awaken weakened rotator cuff and shoulder muscles. Gradually expand stiffened joint range of motion with 1:1 treatment. - Step 3: Integrate
Correct movement patterns to use shoulder naturally in daily activities. Change habits to prevent re-stiffening.
