The thumb tendon strain can be treated in the following ways: 1) to give the thumb sufficient rest, if necessary, you can use a cast or brace to fix the metacarpophalangeal and interphalangeal joints to give the thumb sufficient rest, which can promote the self-repair of the tendon; 2) within 24 hours, you can intermittently apply ice packs, the ice packs can be applied for 5-10 minutes each time, and the interval can be chosen from 1-2 hours. After 48 hours, you can replace the hot compress with an anti-inflammatory and analgesic medication applied locally to the swollen soft tissue around the thumb. For patients with more severe symptoms, oral anti-inflammatory and analgesic drugs can be taken at the same time to relieve the symptoms. Commonly used oral anti-inflammatory and analgesic drugs include Celecoxib capsules, Fotarolim tablets, etoricoxib tablets, ibuprofen, and Dulcolax capsules, which usually repair the tendon of the thumb in about 2-3 weeks.
