Cold Laser Therapy Q&A

What is cold laser therapy?

Also called low-level laser therapy (LLLT), cold laser therapy is a noninvasive treatment that uses varying wavelengths of low-level light to promote cell regeneration. 


When the low-level light passes through your tissues at the pain site, it stimulates oxygen utilization, blood circulation, and adenosine triphosphate production (ATP). This essentially tricks your body into activating its natural healing process.

What is cold laser therapy used for?

Cold laser therapy can help treat a wide range of pain-related conditions, including:


  • Carpal tunnel syndrome
  • Tennis elbow
  • Plantar fasciitis
  • Repetitive stress injuries
  • Rheumatoid arthritis
  • Chondromalacia patella
  • Osteoarthritis
  • Fractures
  • Post-surgical pain
  • Tendinosis
  • Muscle and ligament strain
  • Back pain
  • Knee pain
  • Shingles
  • Diabetic neuropathy
  • Trigeminal neuralgia
  • Fibromyalgia
  • Certain sports injuries
  • Some work- or automobile-related injuries
  • Myofascial trigger point pain


Dr. Chang can even use cold laser therapy to speed up the healing process if you have a slow-healing wound. It’s a safe, effective treatment for chronic pain, and other injuries.

How does cold laser therapy work?

Dr. Chang applies low-level light directly to the pain site. Depending on your condition, he may use varying wavelengths and outputs of the low-level light to effectively target your pain. While you may feel increased blood circulation to the treatment site during your session, cold laser therapy is virtually painless.


Because cold laser therapy is noninvasive, you can resume your normal activities following your appointment. Most treatments take anywhere from five to 20 minutes, and you may need between eight and 30 sessions to relieve pain and restore function to your injury site.


While some patients experience noticeable pain relief and an increase in mobility within hours of their first cold laser therapy treatment, most see their most dramatic results within weeks of their final treatment.


If you have chronic pain or a slow-healing injury, cold laser therapy may be right for you. It is not recommended, however, if you’re pregnant or have any cancerous lesions. Experts do not advise cold laser therapy for the treatment of the thyroid or eyes.
