You sit down in your massage chair at home expecting to feel relaxed. You choose a massage program, lean back and let the rollers work on your back. But later, you notice something you didn't expect: your back feels sore. So, why does your back hurt after using a massage chair?

The good news is that mild soreness doesn't automatically mean you've injured your back. Massage can put pressure on muscles and other soft tissues and some people experience temporary soreness afterward. The National Center for Complementary and Integrative Health (NCCIH) says massage generally has a low risk of harmful effects, although rare serious complications have been reported, particularly with vigorous massage.  The important part is understanding why you're sore and whether the discomfort is temporary or something more serious.

You Used Too Much Massage Intensity

One of the simplest explanations is that the massage was simply too strong. It can be tempting to choose the highest intensity because stronger pressure feels like it must be more effective. Your muscles may have a different opinion. Deep or vigorous massage can leave muscles feeling tender, especially if you're new to massage or haven't used a massage chair for a while. Cleveland Clinic notes that temporary soreness after massage is common and may last for several hours or around a day and a half.  If your back feels sore after a strong session, try reducing the massage intensity next time. You can also lower the airbag pressure and choose a gentler massage technique. More pressure isn't automatically better.

Your Sitting Position May Be Off

Your position in the chair can also affect how the massage feels. If you're sitting too far forward, slouching, twisting your body or not allowing your back to rest properly against the cushion, the massage rollers may not contact your body in the way you expect.

This is one reason body scanning can be useful. The Real Relax Favor-06 2026 automatically scans areas such as the neck, shoulders and back before an automatic massage. The scan helps position the rollers according to your body shape. It isn't a medical examination or a way to diagnose back problems. It simply helps the chair identify where your body is positioned. For better results, sit deeply in the chair and keep your body relaxed while the scan is running.

You May Have Used the Chair for Too Long

Sometimes the problem isn't the massage itself—it's how long you stayed in the chair. A long session with strong roller pressure, air compression and heat can leave your muscles feeling tired or tender. The Real Relax Favor-06 has a timer that can be adjusted in 5-minute increments, and its operating guidance recommends keeping an individual session to one hour or less. If you're new to massage chairs or already experiencing soreness, start with a shorter session, such as 10 to 15 minutes. Pay attention to how your body feels afterward before increasing the duration.

You don't need a marathon massage session to enjoy the benefits of relaxation.

The Massage Technique May Not Suit You

Not every massage technique feels the same. Kneading may feel gentle and comfortable, while tapping or shiatsu can feel much more intense in certain areas. If one program repeatedly leaves your back uncomfortable, try another technique.

The Real Relax Favor-06 offers six manual techniques, including Knead, Knock, Slap, Shiatsu, KD&KN, and KD&Slap. It also allows users to adjust massage intensity and roller width in manual modes. That means you can experiment with different settings instead of using maximum pressure every time. If a particular spot feels sensitive, consider reducing the intensity or choosing a different massage area rather than repeatedly applying strong pressure to it.

Heat May Make the Massage Feel Stronger

Heat can make a massage feel more relaxing, but combining heat with intense mechanical massage may also make the overall experience feel stronger. The Favor-06 includes a back heating function that can be turned on or off. If you notice discomfort after using both heat and strong massage, try using a lower massage intensity without heat during your next session. Then see how your body responds. Sometimes a small adjustment is all it takes.

Your Back Pain May Have Another Cause

Here's something easy to overlook: the massage chair may not actually be the reason your back hurts. Maybe you spent the entire day sitting at a desk. Perhaps you lifted something heavy, exercised, traveled for several hours or simply slept in an awkward position.

Back pain has many possible causes. Mayo Clinic notes that common causes include muscle or ligament strain, while some cases are related to problems involving the spine or other parts of the body.  So if your back was already uncomfortable before the massage, the chair may simply have made you notice the discomfort more clearly. Look at the bigger picture instead of assuming the chair is automatically responsible.

What About Zero Gravity?

Zero Gravity is a popular massage chair feature because it places the body in a reclined position while elevating the legs. The Real Relax Favor-06 includes Zero Gravity, which reclines the back and raises the feet. But comfortable doesn't mean identical for everyone. If Zero Gravity feels good, use it. If a particular reclined position makes your back uncomfortable, change the position or turn the feature off. You don't have to use every feature just because your massage chair has it.

What Should You Do If Your Back Hurts?

If the soreness is mild, give your body some time to recover. Avoid immediately following the session with another intense massage or strenuous workout. For your next session, try:

• Lowering the massage intensity
• Reducing airbag pressure
• Shortening the session
• Choosing a gentler massage technique
• Checking your sitting position
• Turning off the heat if it seems to increase discomfort

Cleveland Clinic suggests rest, hydration, light activity such as walking and gentle stretching for ordinary post-massage soreness. The Favor-06 gives you several adjustable settings, so you can create a gentler experience instead of always choosing the strongest option.

When Should You Stop Using a Massage Chair?

Not all back pain is ordinary post-massage soreness. Stop using the chair and seek medical advice if your pain is severe, keeps getting worse, or doesn't improve. Mayo Clinic recommends medical evaluation when back pain persists for several weeks, spreads down the legs, or is accompanied by weakness, numbness, or tingling. Back pain following a serious injury or accompanied by new bowel or bladder problems also requires prompt medical attention. 

You should also talk with a healthcare professional before using a massage chair if you have a medical condition or recent injury that could make massage unsuitable. NCCIH recommends discussing massage with a healthcare provider when you're unsure whether it is appropriate for you.

A Massage Chair Should Feel Comfortable

So why does your back hurt after using a massage chair? It could be because the massage was too intense, the session lasted too long, your position wasn't right, or the technique simply didn't suit your body. It could also be that your back was already irritated before you sat down. Mild, temporary soreness can happen after massage, but significant or persistent pain shouldn't be ignored.

Start gently, adjust the settings, pay attention to how your body responds, and don't assume that the strongest massage is the best one. With adjustable features such as those on the Real Relax Favor-06, you can fine-tune the experience and make your massage routine more comfortable.
