#Carpal Tunnel Syndrome (CTS)#
Hand pain and weakness are common symptoms that may be caused by a number of underlying causes. These symptoms may develop suddenly or gradually and may affect daily activities such as writing, grasping or lifting objects, etc. Understanding the possible causes can help guide appropriate treatment and prevention strategies. Below are some of the most common medical, neurological, and musculoskeletal conditions that can cause hand pain and weakness.One of the most common causes of hand pain and weakness is carpal tunnel syndrome. Repetitive hand movements, wrist conditions, or health conditions such as diabetes or hypothyroidism may contribute to its development.Symptoms:** Numbness, tingling or burning in parts of the thumb, index, middle finger and ring finger.Weakness of the hand, especially difficulty gripping small objects.Symptoms that worsen at night.
#Arthritis&Tendonitis and tenosynovitis#
Arthritis, particularly osteoarthritis and rheumatoid arthritis, can affect the joints of the hands, causing pain, swelling, stiffness and weakness.
**Symptoms:**Pain and tenderness in the joints.Swelling and stiffness.
Decreased movement and strength of the hand.In the hand, it usually affects the wrist and thumb.
**Symptoms:**
- Pain and swelling near the affected tendons.
- Difficulty moving the fingers or wrist.
- Weak grip.
- Clicking or snapping sensation.
**Nerve compression or entrapment**
In addition to the median nerve in carpal tunnel syndrome, other nerves can also become compressed or entrapped, causing pain and weakness. Ulnar nerve compression (at the elbow or wrist) or radial nerve injury can also affect hand function.
#Symptoms&Diabetic neuropathy#
Arm weakness, especially in fine motor tasks. Clumsiness or dropping objects.
**Cervical radiculopathy (pinched nerve in the neck)**
Nerves in the cervical spine (neck region) control the arms and hands. If these nerves become pinched due to a herniated disc or bone spur, this can cause symptoms in the arm.People with diabetes are at risk for peripheral neuropathy, which affects the small nerves in the hands and feet. Over time, high blood sugar damages nerves, leading to altered sensations and motor weakness.
**Symptoms:** Burning or sharp pain.
Numbness or tingling. Muscle weakness or fatigue in the hands.
Loss of coordination or balance.
**Injuries and overuse**Injuries such as fractures, sprains or dislocations can cause obvious hand pain and weakness. Even minor repetitive activities such as typing, knitting or using tools can cause microtrauma and overuse injuries.Symptoms:**Pain in the area of injury.Swelling, bruising or visible deformity. Limited range of motion or strength.This condition occurs when the finger is stuck in a bent position and can be straightened with a jerk – like a trigger being pulled and released. It is caused by inflammation and narrowing of the sheath surrounding the tendon.
Hand fatigue and loss of grip.Many systemic diseases can cause hand symptoms, including:
**Lupus** – autoimmune disease that can cause inflammation in the joints.
**Multiple sclerosis (MS)** – neurological disorder affecting motor control.
