In this article, you will find out everything you need to know about thumb arthritis and the most effective ways to treat it, including an advanced treatment called Prolotherapy.
Introduction
Thumb arthritis is a common and often disabling condition that can affect your ability to grip, pinch, write, and perform daily tasks. It is especially prevalent in people over 40 and those who use their hands repetitively. This expert-reviewed guide explains the causes, symptoms, and best treatments for thumb arthritis, including advanced options like Prolotherapy.
What is Thumb Arthritis?
Thumb arthritis, also known as basal joint arthritis or carpometacarpal (CMC) joint arthritis, occurs when the cartilage at the base of the thumb wears away. This leads to pain, swelling, stiffness, and reduced movement. Over time, the joint may develop bone spurs, deformity, and weakness (NHS, 2023).
Causes and Risk Factors
- Age: Risk increases with age, especially over 40.
- Repetitive use: Manual work, hobbies, or sports that stress the thumb.
- Previous injury: Sprains, fractures, or dislocations of the thumb.
- Genetics: Family history of arthritis or joint problems.
- Gender: More common in women, especially after menopause.
- Other arthritis types: Rheumatoid arthritis or inflammatory conditions.

Symptoms and When to Seek Help
- Pain and stiffness at the base of the thumb, especially with gripping or pinching
- Swelling or tenderness around the joint
- Reduced range of motion or difficulty moving the thumb
- Weakness or loss of grip strength
- Grinding, clicking, or popping sensations
- Development of a bony bump or deformity
Seek medical attention if:
- Pain is severe or sudden
- You notice significant swelling, redness, or warmth
- You cannot move your thumb or hand
- There is significant deformity or locking of the joint
Diagnosis
A healthcare professional will diagnose thumb arthritis by:
- Taking a detailed medical history and asking about your symptoms, activity levels, and previous injuries
- Performing a physical examination, checking for tenderness, swelling, and range of motion
- Ordering imaging tests (X-ray, MRI, or ultrasound) to assess joint damage, bone spurs, or other causes
- Blood tests if inflammatory arthritis is suspected
Early diagnosis is key to effective treatment and preventing further joint damage.

Treatment Options
Treatment for thumb arthritis depends on the underlying cause, severity, and your overall health. Most people benefit from a combination of self-care, medical treatments, and lifestyle changes.
Self-Care and Lifestyle
- Rest and activity modification: Avoid activities that worsen pain, such as heavy gripping or pinching.
- Ice therapy: Apply ice packs for 10–15 minutes after activity to reduce inflammation.
- Supportive splints: Wear a thumb splint to support the joint and reduce strain.
- Gentle stretching and strengthening: Focus on the thumb, hand, and forearm muscles.
- Ergonomic adjustments: Use adaptive tools or modify your workspace to reduce stress on the thumb.
Medical Treatments
- Pain relief: Over-the-counter medications such as paracetamol or ibuprofen.
- Topical treatments: Anti-inflammatory creams or gels applied directly to the thumb.
- Physical therapy: A physiotherapist can design a program to improve mobility and strength.
- Injections: Corticosteroid or hyaluronic acid injections may be considered for persistent pain.
- Treatment of underlying conditions: Managing rheumatoid arthritis or other systemic diseases is crucial.

Prolotherapy
In recent years, Prolotherapy has built its reputation within the medical community for its clinically proven ability to treat thumb arthritis. Published research has proven its pain-relieving, anti-inflammatory and regenerative benefits.
Prolotherapy involves injecting a natural regenerative solution with tiny needles. This has been shown to stimulate the production of collagen cells, the small cells needed to help with thumb arthritis.
As prolotherapy is helping to treat the root cause of thumb arthritis, it is deemed to be a permanent fix, preventing the symptoms from returning.
