Laser Therapy for Pain:
How Are Morning Back Stiffness and Tendon Knots Treated?

"Every morning my back feels rusty, and it takes me ten minutes or more of moving before it loosens up." "After a two-hour meeting, my back is stiff and painful the moment I stand up or turn." "I can feel little hard knots in my shoulders and elbows, and they hurt when pressed."

We hear these words every day at our Fanling clinic. Many patients have had pain for years and have tried medicated plasters, massage and painkillers, yet the pain keeps coming back. Long-term strain problems like these are exactly where Ever-Health has seen the clearest improvement with laser therapy. Below we explain why, what the research shows, and what we have seen in clinic.

Long-Term Back Pain: Why Is It Stiffest in the Morning and After Sitting?

When the back muscles, fascia and ligaments stay tight or inactive for long periods, blood circulation worsens and waste products and inflammatory substances build up more easily. After a night's sleep or hours of sitting, the tissue stiffens further while still, so the first movement out of bed, or the moment you go from sitting to standing, is especially hard. Only after moving for a while and warming up does it gradually ease.

This kind of pain affects more than the back: it also affects sleep, work and mood. Relying on painkillers for a long time is not ideal either.

Years of Strain: Stiff Tendons, Inflammatory Knots and Adhesion Knots

Repeating the same movement for years, such as carrying children, lifting goods, using a mouse for long hours or standing at work, causes tiny injuries in the tendons and fascia. As the body repairs them again and again, the tissue becomes tight and may even stick together, forming hard knots you can feel:

• Inflammatory knots: there is local inflammation, pressing causes sharp pain, and there is sometimes mild swelling or warmth.
• Adhesion knots: tissues stick to one another and feel like hard bands or lumps, with a pulling sensation when you move.

Chinese medicine usually calls these "tendon knots" (jin jie). They stop muscles from gliding, restrict nearby joints and become a source of recurring pain.

How Does Laser Therapy Target This Kind of Pain?

Laser works through photobiomodulation (see What is laser therapy? for how it works) and helps strained tissue in three ways:

• Better circulation at depth: near-infrared light reaches the muscle and fascia layers, boosting blood flow, clearing built-up inflammatory substances and bringing nutrients for repair.
• Regulating inflammation and easing pain: it reduces local inflammatory substances and temporarily slows pain signals, so stiffness and tenderness ease.
• Supporting tissue repair: it supplies energy to tendon cells and, with stretching and manual therapy, helps tight and stuck tissue gradually regain its flexibility.

What Does the Research Say?

The American College of Physicians (ACP) guideline on chronic low back pain lists low-level laser as one of the non-drug treatments to consider. For high-intensity laser, a 2019 meta-analysis found that high-intensity laser plus exercise was clearly better than sham laser plus exercise at reducing pain and improving movement, and a 2023 meta-analysis also supported its benefit for low back pain. For myofascial neck pain, meta-analysis shows that laser can reduce pain, raise tolerance to pressure and improve neck range of motion. Research on tendinopathy and plantar fasciitis points out that an adequate dose is key to the result.

*An assessment is needed before treatment; acute injuries, fractures or severe pain of unknown cause should be seen by a doctor first.

Ever-Health's Clinical Experience with Laser Therapy

Ever-Health offers laser therapy. Here is what we have observed in clinic:

1. Long-term back pain: shorter morning stiffness, smoother turning

For patients with long-term back pain who are stiff on waking and stiff and painful when changing position after sitting, we have seen laser therapy give clear and lasting results. After completing a course, many patients tell us:

More importantly, these improvements hold for some time after the course ends, rather than only feeling better on the day of treatment. We believe this is linked to laser improving circulation and inflammation in deep tissue; combined with targeted stretching, the results are more stable.

2. Years of strain: tendon knots clearly reduce

For tendon stiffness, inflammatory knots and adhesion knots caused by long-term strain, we have seen in clinic that knots become clearly smaller and softer, and less tender. The tendons feel less tight and joint movement improves as well. Common areas include the neck and shoulders, upper back, elbows, wrists (for example mummy wrist), around the knee and the plantar fascia.

The above are Ever-Health's clinical observations. Every patient responds differently, and the number of sessions also varies.

Ever-Health's Laser Treatment: Four Steps

1. Assessment: a detailed consultation and hands-on examination to tell whether the problem is tendon strain, a joint problem or a compressed nerve, and whether laser is suitable.
2. Laser therapy: the dose is set according to the depth and size of the area. Both patient and staff wear protective eyewear, and most people feel only warmth.
3. Manual therapy and stretching: combined with acupuncture, manual therapy or physiotherapy as needed to release tight fascia.
4. Exercises and follow-up: we teach home stretches and posture changes, and regularly review morning stiffness, tenderness and knots before adjusting the treatment.

Frequently Asked Questions

Does laser therapy work for back pain?

International guidelines list laser as one of the non-drug treatment options for chronic low back pain, and meta-analyses show that high-intensity laser combined with exercise can reduce pain and improve movement. At Ever-Health we see clear and lasting improvement in many patients with morning stiffness and stiff, painful backs after sitting.

Can laser therapy help muscle knots and adhesions?

Yes. Laser improves local circulation and regulates inflammation. Together with manual therapy and stretching, it helps tight and stuck tissue regain its flexibility. In clinic we have seen many patients' knots become clearly smaller and softer, with less tenderness.

How many laser sessions are needed for back pain?

It depends on how long the pain has lasted, the area involved and how severe it is; a full course is usually needed. Ever-Health recommends the number of sessions after an assessment and adjusts it according to changes in morning stiffness and tenderness.

What should I look out for after laser therapy?

You can carry on with normal activities after treatment. We recommend doing the stretches you are shown and avoiding staying in one position for long straight away. Any brief soreness usually settles on its own.

How is laser therapy different from shockwave therapy?

Laser uses light energy to regulate cells and improve circulation and inflammation, and feels gentle. Shockwave uses sound waves to stimulate tissue mechanically and is more often used for calcified or stubborn tendon problems. The two can be combined where appropriate; see our article on shockwave therapy for details.
