De Quervain’s Tenosynovitis: Symptoms, Treatment & UK Online Doctor Support

De Quervain’s tenosynovitis is a painful condition affecting the tendons on the thumb side of your wrist. If you have this condition, it will likely hurt when you turn your wrist, grasp anything, or make a fist. While the exact cause is often unknown, it is generally attributed to the thickening of the sheath that surrounds the two tendons at the base of the thumb.

When these tendons—the abductor pollicis longus and extensor pollicis brevis—become inflamed or the sheath narrows, they cannot glide smoothly. This creates friction and pain during movement. In the UK, this condition is frequently seen in people who perform repetitive hand or wrist motions, such as gardening, racket sports, or lifting young children (often referred to as 'mummy thumb').

Primary Signs

The hallmark of De Quervain’s is pain specifically located where the base of the thumb meets the wrist. Patients often describe the following symptoms:

• Pain near the base of the thumb: This may appear suddenly or develop gradually over weeks.
• Swelling: You may notice a small, tender lump or general puffiness near the radial styloid (the bony bump on the thumb side of the wrist).
• Difficulty moving the thumb: A 'sticking' or 'snapping' sensation when moving the thumb is common.
• Weakened grip: The pain can make it difficult to hold a kettle, turn a doorknob, or lift a child.

If left untreated, the pain may spread further into the thumb or up the forearm. Following NICE (National Institute for Health and Care Excellence) evidence, early intervention is key to preventing long-term stiffness.

You should consider a consultation with an online GP if your wrist pain is interfering with your daily life or work, or if self-care measures like paracetamol and rest have not improved symptoms after two weeks. An online doctor can conduct a visual assessment and guide you through a physical test known as the Finkelstein test.

During a video consultation, the GP will ask you to bend your thumb across the palm of your hand and cover it with your fingers. You will then be asked to bend your wrist toward your little finger. If this causes significant pain on the thumb side of your wrist, it is a strong indicator of De Quervain's. A UK online doctor can also discuss sick notes if your job involves repetitive tasks that exacerbate the condition, and provide advice on ergonomic adjustments.

In the UK, several factors increase the likelihood of developing this tendon issue:

• Repetitive Motion: Activities such as typing, knitting, or manual labour can lead to overuse.
• Pregnancy and Parenthood: Hormonal changes during pregnancy can cause swelling, and the repetitive lifting of a newborn can strain the thumb tendons.
• Age and Gender: It is more common in women and individuals aged between 30 and 50.
• Inflammatory Conditions: Rheumatoid arthritis can sometimes be a contributing factor.

The NHS and NICE recommend a stepped approach to managing De Quervain’s tenosynovitis, starting with conservative measures:

1. Rest and Immobilisation

The most important step is avoiding the activity that triggered the pain. A thumb-spica splint, which keeps the thumb and wrist still, is often recommended for 4–6 weeks to allow the inflammation to subside.

2. Medications

Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (either oral or topical gel) are commonly used to reduce pain and swelling. Paracetamol may be used for simple pain relief.

3. Physiotherapy

A physiotherapist can provide exercises to strengthen the muscles and improve tendon gliding. Hand therapy is a specialised branch of physiotherapy that is particularly effective for this condition.

4. Steroid Injections

If conservative treatments fail, a corticosteroid injection into the tendon sheath may be required. This is highly effective, with many patients experiencing significant relief after one or two injections.

To manage the condition at home, follow the RICE principles where appropriate, specifically focusing on Rest and Ice. Applying an ice pack (wrapped in a towel) to the affected area for 15 minutes several times a day can help reduce the localised swelling. Additionally, try to change how you lift objects—use your whole hand and forearm rather than just your thumb and index finger. If you work at a computer, ensure your workstation is ergonomically sound to reduce unnecessary wrist deviation.
