Could radiation therapy help your arthritis pain?

When medications, injections, or physical therapy haven’t provided enough relief, Low-Dose Radiation Therapy (LDRT) may be an option. This safe, non-invasive treatment uses very small doses of radiation to reduce inflammation in painful joints, helping reduce swelling and discomfort without affecting the rest of the body.

How it works:
During arthritis flare-ups, immune cells release chemicals that cause inflammation. LDRT gently reduces those overactive cells, allowing the joint to settle down and pain to improve.

Conditions that may benefit:
• Osteoarthritis & Rheumatoid arthritis
• Bursitis or tendonitis
• Plantar fasciitis
• Post-surgical joint pain
• Other inflammatory joint or soft tissue conditions

Why patients choose it:
✔ Short, simple treatments
✔ Minimal side effects
✔ No downtime — return to normal activities
✔ Many feel relief after just a few sessions

Talk with your care team to see if radiation therapy could be right for you.
