Thumb pain can be a serious disruption to your daily life, making it difficult to perform everyday tasks like typing, gripping objects, or holding a cup. There are many potential causes of thumb pain, from injuries and repetitive strain to underlying medical conditions. The most common conditions that tend to develop are arthritis, trigger thumb, and De Quervain's tenosynovitis. Pain can also be caused by carpal tunnel syndrome, tendonitis, ganglion cysts, and sprains. Treatment options vary depending on the cause and can include wearing a splint or brace, anti-inflammatory medications, steroid injections, and in some cases, surgery.

What You'll Learn
Thumb arthritis
Arthritis is a condition that affects joints, ultimately resulting in the wearing out of the protective cartilage joint surface. The most common site for arthritis to develop in the thumb is the basal joint at the base of the thumb, also known as the carpometacarpal (CMC) joint. This joint is located near the wrist and the fleshy part of the thumb and enables the thumb to swivel, pivot, and pinch so that you can grip things in your hand.
Osteoarthritis, or degenerative joint disease, is the most common type of arthritis that affects the basal joint. It occurs when the cartilage covering the ends of the bones wears away due to age and use, causing the bones to rub against each other and resulting in friction and damage. Osteoarthritis can cause the joint to become inflamed and painful, and it can lead to a loss of strength and range of motion in the thumb.
Treatment options for thumb arthritis depend on the severity of the condition and may include non-surgical and surgical approaches. Non-surgical treatments, such as icing the joint, taking anti-inflammatory medications, wearing a supportive splint, and performing stretching exercises, can help reduce inflammation, swelling, and pain. In more severe cases, surgery may be considered to reduce pain and improve joint function. One surgical procedure for thumb arthritis is thumb fusion, where the joint is removed, and the ends of the joint are pressed together with a plate and screws to heal. After surgery, a cast or splint is typically worn for several weeks, followed by a rehabilitation program to regain movement and strength in the hand.

De Quervain's tenosynovitis
De Quervain’s tenosynovitis is a painful condition that affects the tendons in your wrist, causing thumb joint pain. It occurs when the two tendons around the base of the thumb become swollen, which then causes the sheaths (casings) covering the tendons to become inflamed. Tendons are cords of tissue that connect muscles and bones.
The two tendons affected by De Quervain's tenosynovitis are the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These tendons arise from muscles in the forearm and run together in a sheath that keeps them close to the bone as they cross from the thumb side of the wrist into the hand. The APL assists with bringing the thumb away from the index finger, while the EPB straightens the thumb joints.
The most common cause of De Quervain's tenosynovitis is chronic overuse of the wrist through repetitive movements. These repetitive movements can cause irritation and pain, leading to inflammation and swelling of the tendons and thickening of the sheath. The condition may also be caused by engaging in activities such as racket sports, golf, handicrafts, or lifting children. People with rheumatoid arthritis may be more susceptible to developing De Quervain's tenosynovitis, and it is more common in people in their 40s and 50s, affecting more women than men.
The main symptom of De Quervain's tenosynovitis is pain over the thumb side of the wrist, which may sometimes extend up the forearm. This pain may appear gradually or suddenly. Other symptoms include a squeaking or snapping noise (called crepitus) as the tendons move through the narrowed tunnel due to swelling or thickening of the sheath.
To prevent De Quervain's tenosynovitis, it is important to avoid repetitive movements and reduce stress on the wrists. Taking frequent breaks and wearing a brace or splint on the thumb and wrist can also help.

Trigger thumb
The most common symptoms of trigger thumb include a snapping or popping feeling when moving the thumb, pain and stiffness when flexing the thumb, soreness in the palm near the base of the thumb, and swelling or a tender lump in the palm. In some cases, the thumb may become locked in a bent position and be difficult to straighten. The symptoms typically come and go and are often worse at night. Patients may experience electric shock sensations or burning pain in the thumb.
Treatment for trigger thumb includes wearing a wrist brace or splint, especially at night, performing stretching exercises, hand therapy, and steroid injections. Surgery is considered when other treatments have failed or if the thumb is stuck in a bent position and cannot be straightened with gentle manipulation. The surgical procedure, called trigger finger release, involves releasing the A1 pulley to allow the tendon to glide more easily through the sheath.

Tendonitis
The inflammation irritates or constricts the tendons around the base of the thumb, causing them to swell. This can be caused by overuse of the thumb or wrist, repetitive grasping or gripping, health conditions that cause inflammation (such as arthritis), or direct impact to the thumb or wrist. Activities such as racket sports, skiing, using tools, and lifting children can also contribute to De Quervain's tenosynovitis.
The Finkelstein test is used to diagnose De Quervain's tenosynovitis. During this test, the patient makes a fist with their fingers wrapped over their thumb and moves their wrist up and down. If the patient experiences pain during this motion, it indicates De Quervain's tenosynovitis.
Treatment for De Quervain's tenosynovitis typically focuses on managing symptoms and allowing the thumb tendons and their sheaths to heal. This can include wearing a splint or brace to immobilize the thumb and wrist, anti-inflammatory medications, and steroid injections. In more severe cases, surgery may be required to open the tendon sheath and remove any excess tissue.
It is important to treat thumb tendonitis promptly, as leaving it untreated can lead to severe damage that limits mobility and takes months to recover. Complications may include permanent limitations in movement, weakness in the affected tendon, and an increased risk of tears and rupture.

Carpal tunnel syndrome
The carpal tunnel is an opening in the wrist formed by the carpal bones at the bottom and the transverse carpal ligament at the top. This tunnel is typically narrow, and any swelling or irritation can compress the median nerve, causing carpal tunnel syndrome. The condition can be influenced by anatomical differences, with some individuals having a smaller carpal tunnel size, which may be a hereditary factor. Women, on average, have smaller carpal tunnels and are more susceptible to developing the syndrome.
Symptoms of carpal tunnel syndrome include pain, numbness, tingling, and weakness in the thumb and fingers. In severe cases, muscle wasting can occur at the base of the thumb, resulting in visible atrophy and a reduction in grip strength. Thumb arthritis, which affects the joint rather than the nerve, may also contribute to pain and swelling at the base of the thumb.
Treatment options for carpal tunnel syndrome aim to alleviate pressure on the median nerve and address the underlying causes. Non-surgical treatments are typically recommended first, including splinting, physical therapy, anti-inflammatory medications, and ergonomic adjustments. Surgery, known as carpal tunnel release, may be considered if non-surgical approaches are ineffective or if there is a risk of irreversible damage to the median nerve.
It is important to consult with a healthcare provider for a proper diagnosis and treatment plan. They may recommend electrodiagnostic tests or nerve conduction studies to confirm carpal tunnel syndrome and assess the severity of nerve compression. Early intervention is crucial to prevent permanent nerve damage and ensure a full recovery.
