Frozen Shoulder: Ice or Heat? What to Use and When

For a frozen shoulder, you can use either one. Heat is usually the better choice before you stretch, because it can loosen a stiff joint. Ice is a good choice afterward, because it can calm soreness and swelling. Official health sources say both can reduce pain, so the best pick is often the one that feels better on your shoulder. 🙂

Below, we explain what each one does, how to build a simple routine around your exercises, and how to keep your skin safe. We also cover the signs that mean it’s time to call a doctor.

TL;DR

• Both heat and ice can ease frozen shoulder pain. NHS inform says you can use whichever feels most helpful.
• A common routine is moist heat before your stretches and ice afterward.
• Keep each session to 20 minutes or less, put a cloth between the pack and your skin, and leave a few hours between sessions.
• Skip both if you have reduced feeling or circulation in the area. Stop if redness, discoloration, or blistering gets worse.
• Heat and ice ease symptoms. Gentle, regular movement and your clinician’s plan do the real work of restoring motion.

The short answer: heat, ice, or both?

Frozen shoulder (also called adhesive capsulitis) means a stiff, painful shoulder joint. The question people ask is whether to reach for the heating pad or the ice pack. The honest answer is that the research doesn’t crown one winner.

• NHS inform says heat and ice both help reduce pain and that you can use whichever you find most helpful.
• A 2017 physical therapy review says either heat or ice may be used for pain relief before gentle exercises during the painful early phase.
• The Veterans Health Library gives each a practical job. Heat may loosen the shoulder, while cold may limit pain and swelling after stretching.

So think of it this way. Heat is your warm-up. Ice is your cool-down. If one of them doesn’t feel good on your shoulder, use the other.

When heat helps a frozen shoulder

Stiffness is the main complaint with a frozen shoulder, and warmth is the tool most often suggested for stiffness. MedlinePlus, a service of the U.S. National Library of Medicine, recommends moist heat before your exercises to lessen pain and increase movement. It says moist heat can be used 3 to 4 times a day.

The Veterans Health Library says heat may loosen a frozen shoulder, and it suggests talking with your doctor about it. The 2017 review adds that moist heat combined with stretching has been shown to improve muscle extensibility. In plain words, a warm shoulder tends to stretch more easily.

Good times to use heat:

• Right before your home stretches or physical therapy exercises.
• In the morning, when the joint feels stiff.
• After a long stretch of sitting at a desk, when your shoulder has tightened up.
• During a warm shower, if you don’t have a pack handy. Letting warm water run over the shoulder is an easy way to loosen up.

Moist heat vs. dry heat

MedlinePlus specifically names moist heat. A damp warm towel, a warm shower, or a gel wrap warmed up per its directions all count. If you use a heating pad, place a layer of cloth between it and your skin. Don’t fall asleep on it.

If you want a wrap that stays put on a shoulder while you move around, our Shoulder Heat Wrap and Soft Gel Shoulder Ice Wrap are made with flexible soft gel that molds to the joint. You can read more about why timing matters in our guide to heat therapy for stiffness.

When ice helps a frozen shoulder

Ice gets less attention for frozen shoulder, but it has a clear place. The Veterans Health Library says a cold pack can limit pain and swelling. It suggests icing the shoulder for a few minutes after your stretches, with the pack wrapped in a thin cloth to protect your skin.

Ice makes sense when:

• Your shoulder feels sore or achy after exercises.
• You’ve overdone it, and the joint feels irritated or throbs.
• Heat doesn’t feel good on a particular day. Some people find warmth makes a sore shoulder feel worse.
• You want a numbing effect so you can rest comfortably.

The 2024 nonoperative rehab protocol from the American Orthopaedic Association follows this same pattern: moist heat before exercises and ice afterward.

What about a new shoulder injury?

Frozen shoulder is different from a fresh sprain or strain. If you hurt your shoulder in a fall or a workout, the usual first step is ice for the early days, with heat later once swelling settles. Our guides on ice versus heat for shoulder pain and using ice for shoulder pain walk through that timing. If you’re not sure whether your pain is a new injury or a frozen shoulder, ask a clinician before you start a routine.

A simple routine: heat, move, ice

Here is an easy way to put the advice together. Adjust it to your own comfort and to whatever your doctor or physical therapist has told you.

1. Warm up the shoulder. Apply moist heat for up to 20 minutes, with a cloth between the pack and your skin.
2. Do your gentle stretches. Stay in a comfortable range. More on this below.
3. Cool it down. Apply a wrapped ice pack for a few minutes if the shoulder feels sore.
4. Rest between sessions. Leave a few hours before the next round of heat or ice.

How hard should you stretch?

This is where many people go wrong. Stretching harder doesn’t thaw a shoulder faster.

• MedlinePlus recommends short, frequent stretching and motion work. It suggests once every hour, or at least four times a day at first, rather than one long session.
• The 2017 review recommends short, relatively pain-free range-of-motion work, about 1 to 5 seconds at first. It warns that aggressive stretching beyond the pain threshold can worsen outcomes.
• The NHS advises gentle movement and the exercises you’ve been given. It warns against inventing strenuous exercises, because they can make pain worse.
• MedlinePlus says to avoid strengthening exercises until your range of motion has returned, because strengthening can aggravate the joint.

The American Orthopaedic Association protocol also describes gentle pendulum swings. They start at 15 seconds and build up to 3 to 5 minutes as tolerated, repeated five times a day. Your physical therapist can tell you whether that fits your stage of recovery.

How long to use heat or ice, and how to protect your skin

Heat and ice are simple, but a few rules keep them safe.

• Use a barrier. Never put heat or ice directly on bare skin. Use a towel, a thin cloth, or the sleeve of a wrap designed for the job. NHS inform gives this advice, and the Veterans Health Library says the same about wrapping the ice pack in a thin cloth.
• Watch the clock. NHS inform says to limit treatment to 20 minutes at a time and leave a few hours between treatments. The NHS gives the same up-to-20-minute limit for a heat pack or hot-water bottle wrapped in a tea towel.
• Check your skin. NHS inform says to stop if redness, discoloration, or blistering increases.
• Know when to skip it. NHS inform says not to use either heat or ice for shoulder pain when circulation or sensation is impaired. That can apply with conditions such as diabetes or nerve problems. If that sounds like you, ask your doctor first.

Quick comparison

What heat and ice can’t do

A warm pack feels great, but it doesn’t treat the underlying stiffness on its own. The American Academy of Orthopaedic Surgeons says treatment focuses on controlling pain and restoring motion and strength through physical therapy, including stretching and range-of-motion exercises. Heat and ice sit inside that plan. They make the exercises more comfortable so you can keep doing them.

Some people also need more than home care. Your clinician may talk with you about medication, injections, or other options. A frozen shoulder can take a long time to improve, so pace yourself and keep your expectations realistic.

Our take on heat and ice for a frozen shoulder

We make reusable ice and heat wraps, so we see the same question all the time. Here is what we tell people.

First, pick based on the job, not the hype. Warmth before movement, cold after movement, and whichever one feels better on a rough day. You don’t need to buy a gadget for each step, but you do need something that stays in place. A bag of peas slides off a shoulder. A flexible soft gel wrap that hugs the joint lets you sit back and relax instead of holding it.

Second, comfort and mobility matter. If a pack is stiff and heavy, you won’t use it as often as you should. Soft gel that bends with your body is easier to wear while you do light tasks at home.

Third, treat the 20-minute rule as a rule. More time on the skin doesn’t mean more relief. A cloth barrier, a timer, and a few hours between sessions are cheap and effective.

And finally, heat and ice are support, not the cure. If your shoulder isn’t improving, or you’re not sure what stage you’re in, a physical therapist is the right next call.

— Cool Relief

Make heat and ice easy at home

If you’re setting up a routine, one wrap that does both jobs keeps it simple. Our Soft Gel Shoulder Ice Wrap is reusable and made with soft gel that adapts to the shoulder, so you can apply cold after your stretches. For the warm-up step, we also offer a Shoulder Heat Wrap. Both are part of our full range of ice and heat wraps, which also includes a universal wrap for elbows, thighs, ankles, wrists, and more if other joints ache too.

When to talk to a doctor

Home care is fine for many people, but some signs call for a professional.

• Pain gets much worse. MedlinePlus says to seek medical advice if shoulder pain gets much worse despite pain medicine.
• You reinjure the shoulder or arm. MedlinePlus lists this as a reason to call too.
• You can’t tell what’s causing the pain. Shoulder pain can come from the joint, the muscles, or the rotator cuff. A clinician can tell them apart, and the right treatment depends on the cause.
• You have numbness or poor circulation. Ask before using heat or ice at all, since NHS inform advises against both in that case.
• Your skin reacts. Stop if redness, discoloration, or blistering increases, and get it looked at if it doesn’t settle.

If you’ve had shoulder surgery, follow your surgeon’s instructions on heat and ice before anything you read here.
