How long does subacromial decompression take to work for shoulder impingement?

Subacromial decompression changes the space and tissues around the shoulder to reduce irritation during movement. Early recovery can include soreness, stiffness, and limited lifting. The operation itself does not instantly restore shoulder strength; healing, movement practice, and rehabilitation help you regain useful function.

Your pace depends on the condition of the tendon and joint, the findings treated during surgery, your preoperative strength, and the demands of your work or sport. Improvement should be judged across movement, sleep, dressing, reaching, and lifting rather than by one good or bad day.

Follow the surgeon’s instructions for wound care, sling use, driving, lifting, and exercises. Perform the prescribed range-of-motion work gently and attend physiotherapy if advised. Increase reaching and resistance in stages; forcing a painful movement can aggravate healing tissues.

Keep the incision clean and watch the shoulder’s response after exercise. Share any medication concerns, numbness, or difficulty following the programme so the team can adapt care.

Contact the surgical team for increasing redness, warmth, drainage, fever, worsening swelling, or pain that is not controlled as expected. Seek urgent help for severe chest symptoms, sudden breathing difficulty, a cold or blue hand, or new major weakness.

Ask when you may drive, sleep on the operated side, return to work, and begin resisted overhead activity. Ask which symptoms are expected at your stage and how progress will be checked at follow-up.
