**What is Carpal Tunnel‌ Syndrome (CTS)?**


Carpal tunnel syndrome (CTS) is a medical‍ condition that affects ⁤the median nerve, which runs through a narrow passageway in the wrist known​ as the carpal tunnel.


CTS occurs when the tissues surrounding the tendons in the​ carpal tunnel become ⁤inflamed, causing pressure on the ‍median nerve. This can be caused by repetitive hand​ movements, ‍obesity, pregnancy, and certain medical conditions such as diabetes ‍or rheumatoid arthritis.


* Numbness, tingling, or pain ​in the palm of ⁤the hand, ⁣thumb, index, middle, and ring‌ fingers

* Weakness in the hand,​ making ‍it difficult​ to grasp objects or make a fist

* Shooting pain​ that extends up the ⁤forearm

* A burning or prickling sensation in the fingers

* Numbness or weakness that is worse at night or after prolonged ‍hand use


CTS is typically diagnosed through⁣ a physical exam⁣ and a series of tests, including:

* Wrist flexion and extension ⁣tests

*⁣ Tinel’s test‍ (tapping over the median nerve)

* Phalen’s test (flexing the wrists ⁣for 60 ‍seconds)

* Electrodiagnostic⁢ studies (EMG and nerve conduction studies)


Treatment for CTS aims to reduce pressure on⁢ the median nerve and alleviate symptoms. ⁤Options include:

* **Non-surgical⁤ Treatment:**

* Wrist splints or braces to immobilize the wrist

* Physical therapy

* Ergonomic ‍modifications to reduce⁣ hand strain

* Over-the-counter ⁤pain relievers (e.g., ibuprofen, naproxen)

* **Surgical ‍Treatment:**

‌ * ⁢Carpal tunnel release, which involves cutting the ligament and creating more space in the​ carpal tunnel

**Long-Term Outlook**

With proper treatment, most people with CTS experience⁢ significant⁤ improvement or complete resolution of symptoms. However, early diagnosis and intervention are‍ key to preventing permanent nerve damage.


While not all⁤ cases of CTS are ⁤preventable, ⁤there are⁢ steps you can take to reduce your risk:

* Take breaks from repetitive hand movements

*​ Use ergonomic tools and ⁤postures

* Wear wrist braces or splints during activities​ that strain your wrists

* Maintain a healthy weight

* Manage underlying medical conditions that⁣ contribute to CTS (e.g., diabetes, obesity)

**Additional Information**

* CTS is ⁣the most ⁣common​ entrapment neuropathy in the upper⁣ extremity.

* It affects women more frequently than men.

* The ‌severity of CTS⁣ can vary from mild to severe, with some individuals experiencing only occasional discomfort and others experiencing debilitating pain.

* In severe cases, CTS can lead to loss of function in‌ the ⁢hand and ⁤difficulty with ⁢everyday ​activities.
