Red light therapy for psoriatic arthritis: what should you know?

Red light therapy may be considered for symptom support, but it should not replace assessment or prescribed psoriatic arthritis treatment. Psoriatic arthritis can affect joints, tendons, skin, and nails, so a plan needs to match the pattern of inflammation and its effect on movement.

Red light devices deliver visible or near-infrared light to a targeted area. People may ask about them when joint pain, swelling, or morning stiffness continues. The treatment may feel warm, and results can differ by device, dose, and the problem being treated. It is not a substitute for medicines that control inflammation throughout the body, nor does it address every feature of psoriatic arthritis.

Discuss the device and treatment area with your rheumatology or rehabilitation clinician before starting. Keep a record of pain, swelling, stiffness, skin changes, and hand or foot function so you can judge whether the approach is helping. Continue your agreed medicines unless the prescriber changes them. Physiotherapy can support joint protection, strength, mobility, and pacing alongside medical care.

Arrange prompt medical review for a newly swollen or very painful joint, rapidly worsening stiffness, a hot joint, fever, or a new eye problem such as pain, marked redness, or light sensitivity. Stop a light session and seek advice if it causes a burn, blistering, unusual skin reaction, or worsening symptoms.

Ask whether your current symptoms suggest active inflammation; what the device is intended to treat; how it fits with anti-inflammatory medication and physiotherapy; which medicines or skin conditions make light exposure unsuitable; and how progress will be reviewed.
