Frozen Shoulder: Complete Guide

Frozen shoulder causes progressive shoulder stiffness and pain over months, often resolving eventually but sometimes taking 1-3 years for full recovery.

Prevalence
2-5% of adults
Peak age
40-60 years
Diabetes link
2-4× higher risk
Natural course
Can take 1-3 years

The Three Stages

StageDurationFeatures
Freezing (painful)2-9 monthsGradually worsening pain, progressive stiffness begins
Frozen (stiff)4-12 monthsPain may reduce but stiffness is significant, limiting movement
Thawing (recovery)5-24 monthsGradual improvement in range of movement

Why Diabetics Are at Higher Risk

Diabetes increases frozen shoulder risk 2-4 fold, likely related to changes in connective tissue from chronically elevated blood sugar. Good diabetes control may reduce this risk and improve outcomes.

Treatment Options

TreatmentBest Stage
Physiotherapy/stretching exercisesAll stages — helps maintain mobility
Steroid injectionMost effective in the freezing (painful) stage
Hydrodilatation (fluid injection to stretch capsule)Can be effective, especially frozen stage
Manipulation under anaesthesiaFor persistent stiffness not responding to conservative treatment
Arthroscopic capsular releaseSurgical option for severe, prolonged cases
Gentle Movement, Not Complete RestWhile frozen shoulder is painful, complete immobilisation can worsen stiffness — gentle, regular range-of-motion exercises (even if uncomfortable) as guided by a physiotherapist help maintain and eventually improve mobility.
Will frozen shoulder go away on its own?
Yes, frozen shoulder is generally self-limiting, though the full cycle can take 1-3 years. Treatment can speed recovery and reduce pain during this process, but patience is often needed.
Can frozen shoulder come back or affect the other shoulder?
It rarely recurs in the same shoulder, but up to 20-30% of people develop it in the other shoulder at some point, particularly if diabetic.
