“I Just Wanted to Walk Again” Overcoming the Pain of Dying Bone: Recovering Daily Life with PBM

|

Client Profile

• Name : Sung Young-nam (Current CEO of Light Healing Immune Center)

• Medical History : Survived acute leukemia twice, diagnosed with Avascular Necrosis (AVN)
  of the femoral head, chronic renal failure (peritoneal dialysis).

• Key Symptoms : Extreme bone pain comparable to childbirth, gait disturbance,
  and sleep disorders in a condition where analgesics could not be used.

1. The Challenge: Despair Without Even Painkillers

Before turning thirty, Mrs. Sung Young-nam overcame acute leukemia twice. However, the joy of survival was short-lived.
As a sequela of chemotherapy, she was diagnosed with ‘Avascular Necrosis (AVN) of the femoral head.’
This is a disease in which bone tissue slowly dies due to blockage of microscopic blood vessels leading to the hip joint,
accompanied by extreme bone pain often compared to the pain of childbirth.

She could hardly take a step without a cane, and she couldn’t sleep due to the pain that continued every night.
The greater despair was the limitation of treatment. As she was undergoing peritoneal dialysis for chronic renal failure,
even prescribing painkillers to reduce the pain was limited. She had to hear from the hospital that “there is nothing more we can do,”
and she had to find a way to live on his own.

2. The Solution: ‘PBM Therapy’ Beyond Simple Heat

The core problem of this disease is ‘blockage of blood flow.’ Mrs. Sung tried various heating devices and panels on the market for blood circulation.
However, only the surface of the skin became hot, while the pain deep in the bone remained the same, and she even suffered low-temperature burns.

In the meantime, she encountered Huelight’s professional Whole-Body PBM (Photobiomodulation) technology.
On the first day she received PBM care, where specific wavelengths of light penetrate deep into cells rather than simple heat, she felt a change in pain for the first time.

3. Clinical Outcomes: Regained Changes in Daily Life

After consistently undergoing Huelight’s Whole-Body PBM care more than twice a week, her life changed concretely.

• Significant Reduction in Pain: Immediately after care, the bone pain crushing her hip joint decreased, and the heavy sensation in her legs was resolved.

• Recovery of Walking Function: She broke away from a life dependent on a cane and became capable of daily walking on his own.

• Improvement in Sleep Quality: As the nights tossing and turning from pain disappeared and she slept deeply, her overall body condition and resilience improved significantly.

“Finally, I felt like I was living like a human being.” — Sung Young-nam (CEO of Light Healing Immune Center)

4. Scientific Context: How Does Science Explain This Change?

Mrs. Sung’s recovery can be explained by the biochemical mechanisms of PBM.
Recent academic studies support the positive effects of PBM on intractable pain and tissue regeneration.

① Mitochondrial Activation and Energy (ATP) Recovery The core principle of PBM is to wake up the mitochondria, the engines within cells.
When wavelengths in the 600–1,000nm range are absorbed by cytochrome c oxidase (CCO) in mitochondria, ATP production, the cellular energy source, surges.
This plays a role in replenishing the body’s energy depleted by fighting the disease from the cellular level [1][2].

② Inflammation Control and Natural Analgesic Effect According to a systematic review on chronic pain published in 2026,
PBM showed significant effects in inhibiting inflammatory mediators and lowering pain levels without drugs.
Especially for patients who have difficulty using drugs due to kidney disease, PBM can be a safe and effective alternative [3][4].

③ Potential for Angiogenesis and Tissue Regeneration Studies have reported that PBM stimulates vascular endothelial growth factor (VEGF)
to help create new blood vessels and activates osteoblasts that make bone. This suggests the possibility of regenerating necrotic areas
where blood supply has been cut off [5].

5. Vision: From Patient to ‘Healer’

Based on her recovery experience, Mrs. Sung established the ‘Light Healing Immune Center’ in Yongin. Initially, it was for her own treatment,
but now she is delivering hope to patients suffering from the same pain. Currently, at her center, her father with a history of lung cancer
and her mother suffering from chronic back pain also receive daily PBM care to maintain a healthy daily life.

“Rather than the obsession with a complete cure, it is important to create ‘an environment where my body can recover on its own.’ I want to share the strength to slowly live daily life again, rather than getting better quickly.”
