Is laser therapy for pain done with a Class IV therapy laser?

A Class IV therapy laser delivers therapeutic light to selected tissues through a handheld applicator. The clinician chooses the area, treatment settings, and session length according to the body region, symptoms, skin, and treatment goal. You may feel warmth, but the experience varies by device and person. Laser therapy is usually used as one part of a rehabilitation plan, alongside movement work, load management, manual techniques, or other care. The name of the device does not by itself establish that laser therapy is suitable for a particular pain problem. A proper assessment should first consider the source of pain and whether another condition needs different treatment.

Tell the clinician if you have unusual light sensitivity, an eye condition, an active skin problem, reduced sensation, or a condition requiring specialist monitoring. Ask whether protective eyewear is required and which areas will be treated. Keep the applicator away from the eyes and do not stare at the beam. Ask how laser therapy fits with your exercises and what improvement or irritation should be reported.

Tell the therapist during the session if you feel intense heat, sharp pain, dizziness, or unexpected discomfort. Afterward, seek medical advice for blistering, a persistent burn-like change, marked swelling, a new rash, or worsening symptoms. Urgent assessment is needed for sudden weakness, severe numbness, loss of coordination, chest pain, or breathing difficulty because these symptoms need evaluation beyond routine pain treatment.

What is causing my pain? Why is laser therapy being considered? What settings and body area will you use? What eye or skin precautions apply to me? Which exercises should accompany the sessions, and when will we reassess the plan?
