Carpal Tunnel Syndrome (CTS) is a common medical condition that affects the hand and wrist. It arises when the median nerve, which extends from the forearm into the palm, becomes compressed as it passes through a narrow passageway in the wrist known as the carpal tunnel. This compression can lead to a range of sensations in the hand and fingers, impacting daily activities and overall comfort.
Understanding Carpal Tunnel Syndrome Symptoms
The primary symptoms of Carpal Tunnel Syndrome typically involve the thumb, index, middle, and a portion of the ring finger. Individuals commonly experience numbness, tingling, and pain in these areas. These sensations often feel like “pins and needles” or that the fingers have “fallen asleep.”
Symptoms are often more troublesome at night, sometimes waking individuals from sleep. This worsening can occur because sleeping with bent wrists increases pressure on the nerve. Symptoms also become noticeable during the day, particularly with repetitive hand movements like typing, writing, or holding objects.
As the condition progresses, weakness in the hand and reduced grip strength may develop, making fine motor tasks difficult.
The Link Between Carpal Tunnel and Itching
While not a typical symptom, some individuals with Carpal Tunnel Syndrome report itching in the affected hand, particularly the palm and fingers. This sensation is often described as a deep itch that scratching may not relieve. Itching, along with other unusual sensations like burning or electric shock, can be linked to median nerve irritation or compression.
Itching in the hands is more commonly associated with other conditions. These include skin issues like eczema or psoriasis, allergic reactions, or systemic conditions such as diabetes, liver disease, or certain medication reactions. Therefore, if itching is present, especially without the classic numbness, tingling, or pain, other potential causes should be considered. However, when itching occurs alongside the more characteristic symptoms of Carpal Tunnel Syndrome, it can indicate nerve involvement.
When to Seek Medical Advice
If you experience persistent or worsening symptoms in your hands and wrists, including numbness, tingling, pain, weakness, or unusual sensations like itching, consult a healthcare professional. An accurate diagnosis is important because Carpal Tunnel Syndrome symptoms can overlap with those of other conditions, such as cervical radiculopathy (nerve compression in the neck), tendonitis, or arthritis. A doctor can evaluate your symptoms, conduct a physical examination, and may recommend diagnostic tests like electrodiagnostic studies to confirm Carpal Tunnel Syndrome. Early evaluation allows for timely intervention, which can help manage symptoms and prevent long-term nerve damage.
