Rest and Activity Modification
Reducing repetitive hand movements or gripping activities allows the inflamed tendon to heal naturally, relieving pressure on the tendon sheath. Avoiding aggravating activities is especially necessary during the early stages of the condition.
Splinting
Wearing a splint to keep the affected finger straight, particularly at night, reduces strain on the tendon and encourages healing by limiting movement. Splinting can be used for several weeks to manage symptoms effectively.
Medication
Over-the-counter non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen, are effective for managing pain and reducing inflammation around the tendon sheath.
Corticosteroid Injections
Injecting a steroid directly into the tendon sheath reduces inflammation, allowing the tendon to glide smoothly again. This treatment is often effective for mild to moderate cases and may provide relief for several months.
