Shoulder surgery leaves you with one working arm, a sling, and instructions to keep the joint cold, three things that make “just hold an ice pack on it” harder than it sounds. Here’s what actually works, and why the shape of the joint matters more for a shoulder than almost anywhere else.

Why Are Shoulders Harder to Ice?

A knee or an ankle is roughly flat enough that an ice pack stays put with gravity’s help. A shoulder is curved, mobile, and usually wrapped around a sling, so a flat pack slides the moment you move, and you’re doing it one-handed. This is the single biggest complaint after rotator cuff repair, arthroscopic surgery and shoulder replacement alike: the swelling management is right, the execution is the problem.

What Changes by Procedure?

  • Arthroscopic shoulder surgery: usually the shortest recovery of the three, often a shorter sling period, but the same early swelling window.
  • Rotator cuff repair: commonly 4 to 6 weeks in a sling, with cold therapy scheduled around physiotherapy as range of motion work begins.
  • Shoulder replacement: a longer overall recovery, with consistent cold therapy mattering most in the first two to three weeks.

Whichever procedure, the early priority is the same: manage swelling without needing a free hand to hold anything in place.

What Actually Reduces Shoulder Swelling?

A shaped wrap solves the positioning problem regardless of what’s inside it. The next question is whether it holds a temperature. An ice pack starts cold and warms within 15 to 20 minutes. A circulating cold therapy machine like the NICE1 uses a side-specific shoulder wrap (left or right, two size ranges) with cold that holds steady at whichever of 5 settings you choose, 42°F to 58°F, plus adjustable compression, for as long as the session runs, no repositioning and no melted ice.

Why Is Sleep the Hardest Part?

Ask anyone who’s had shoulder surgery what the worst part of the first two weeks was, and “trying to sleep with one arm in a sling” comes up constantly. A cold therapy setup that runs overnight without attention, holding its temperature the whole time, removes one more thing from a list that’s already too long during that stretch.
