Does laser therapy for pain help with joint pain?

Laser therapy, also called photobiomodulation, uses a device over the skin near a painful joint. A clinician selects the wavelength, power, and treatment area for the problem being addressed. The aim is to influence local tissue processes and reduce pain or irritation. It does not repair every form of cartilage, tendon, or bone damage, and relief does not confirm a diagnosis. Joint pain from arthritis, an injury, inflammation, or referred pain may need different care alongside or instead of laser treatment.

First identify why the joint hurts through a clinical assessment. Ask the physiotherapist what outcome will be measured, how many visits are being considered, and what exercises or activity changes should accompany treatment. Tell the clinician about implanted electronic devices, pregnancy, medicines that increase light sensitivity, or skin conditions near the treatment area. Protect your eyes as instructed and report unusual heat, skin irritation, or increased pain.

Arrange prompt medical assessment for a hot, markedly swollen joint, fever, a sudden inability to bear weight, or pain after a significant injury. Urgent care is also appropriate for a deformed joint, new numbness, or a limb that becomes pale or cold. Laser therapy should not delay evaluation of these warning signs.

Ask what is causing the joint pain, whether laser therapy fits that diagnosis, and how improvement will be judged. Discuss alternatives, eye protection, precautions for your medicines or devices, and when to stop or change the plan if symptoms persist.
