De Quervain tenosynovitis is a condition that affects the tendons on the thumb side of the wrist, causing pain and discomfort. Here are some steps you can take to rehabilitate this condition:

Rest your wrist: Avoid activities that cause pain or discomfort. This may mean taking a break from repetitive tasks such as typing or knitting.
Ice your wrist: Apply ice to the affected area for 15-20 minutes at a time, several times a day. This will help reduce inflammation and alleviate pain.
Wear a brace: Wearing a wrist brace or splint can help immobilize the affected area and reduce strain on the tendons. It is important to wear the brace consistently to allow the area to heal.
Stretching exercises: Gentle stretching exercises can help improve range of motion and flexibility in the affected area. Your doctor or physical therapist can recommend specific exercises for you to do.
Medications: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help relieve pain and inflammation.
Corticosteroid injections: If the above steps do not provide sufficient relief, your doctor may recommend a corticosteroid injection into the affected area to reduce inflammation.
Physical therapy: Your doctor may recommend physical therapy to help rehabilitate the affected area and prevent recurrence of the condition. Your physical therapist can teach you exercises to strengthen and stretch the affected area.

While there are some steps you can take on your own to manage the symptoms of De Quervain tenosynovitis, it is important to seek guidance from a physical therapist for a proper diagnosis and treatment plan. Self-rehabilitation without the supervision of a healthcare provider may not be effective and can potentially worsen the condition.

Your PT can provide a comprehensive evaluation and recommend a customized rehabilitation plan that may include stretches, exercises, and other therapies. A physical therapist or occupational therapist can also work with you to ensure that you are performing the exercises correctly and avoiding activities that may aggravate the condition.

It is important to talk to your doctor about any symptoms you are experiencing and to follow their recommended treatment plan. With proper care and treatment, most people with De Quervain tenosynovitis can fully recover.
