Numbness, Tingling & Nerve Issues in the Hands & Arms
Waking up with numb fingers. Dropping your coffee mug. Feeling pins and needles while you drive, type, or talk on the phone. Numbness and tingling in the hand and arm are among the most common reasons people visit an orthopedic surgeon, and they’re often a sign that a nerve is being compressed or irritated somewhere between the neck and the fingertips.
This guide explains how the nerves in your arm work, the conditions that most often cause numbness and tingling, how they’re diagnosed and treated, and when symptoms need urgent attention. It’s written for Friendswood residents looking for an orthopedic surgeon who specializes in the hand and upper extremity: Dr. David R. Sollaccio.

Dr. Sollaccio trained at the University of Miami Miller School of Medicine, the University of Florida College of Medicine, and the USC Keck School of Medicine. He focuses on the hand and upper extremity, including nerve compression conditions and nerve injuries, and takes time to explain each patient’s diagnosis and options in clear terms.
How the Nerves in Your Arm Work
Three main nerves travel from the neck down the arm and into the hand, carrying signals for both sensation and movement:
- The median nerve passes through the carpal tunnel at the wrist and provides feeling to the thumb, index, middle, and part of the ring finger. It also powers some of the muscles at the base of the thumb.
- The ulnar nerve runs along the inside of the elbow, the spot often called the “funny bone,” and supplies feeling to the small finger and part of the ring finger, along with many small muscles in the hand.
- The radial nerve wraps around the upper arm and helps you straighten your wrist and fingers.
When a nerve is squeezed in a tight space, stretched, or injured, its signals are disrupted. That often shows up first as tingling or numbness, then as weakness, clumsiness, or trouble with fine movements. The specific fingers affected can help pinpoint which nerve is involved and where.
Causes & Symptoms of Carpal Tunnel Syndrome
Carpal tunnel syndrome is the most common nerve compression condition in the upper extremity. It occurs when the median nerve is squeezed as it passes through a narrow passage in the wrist.
Common symptoms include numbness and tingling in the thumb, index, middle, and ring fingers; symptoms that wake you at night or appear while driving or holding a phone; shaking your hand to “wake it up”; and, over time, weakness or dropping objects.
Risk factors include repetitive hand and wrist use, prolonged wrist bending, pregnancy, diabetes, thyroid conditions, arthritis, and previous wrist injuries.
Treatment often begins with a night splint to keep the wrist straight, activity changes, and sometimes a steroid injection. When symptoms persist or there are signs of nerve damage, such as constant numbness or muscle weakness, carpal tunnel release surgery can relieve pressure on the nerve. It’s typically an outpatient procedure.
Cubital Tunnel Syndrome & Other Nerve Problems
Cubital tunnel syndrome. The second most common nerve compression condition affects the ulnar nerve at the elbow. Keeping the elbow bent for long periods, such as while sleeping, talking on the phone, or leaning on an armrest, can stretch and compress the nerve. Symptoms include numbness and tingling in the ring and small fingers, aching on the inside of the elbow, and, in more advanced cases, weakness that makes pinching, gripping, or typing difficult. Elbow padding, avoiding prolonged bending, and night splints can help. If symptoms persist or weakness develops, cubital tunnel release surgery can take pressure off the nerve.
Radial nerve compression. Less commonly, the radial nerve can be compressed in the forearm, causing aching on the outside of the forearm that’s sometimes mistaken for tennis elbow.
Nerve injuries. Nerves can also be damaged by cuts from glass, knives, or tools, or by fractures and dislocations. Numbness in a finger after a cut is a warning sign that a nerve may be injured. These injuries should be evaluated promptly, since repairing a cut nerve sooner often leads to better recovery.
Diagnosis, Treatment & When Numbness Is an Emergency
Getting the right diagnosis. Numbness in the hand can come from the wrist, the elbow, or even the neck, and sometimes from more than one place. Dr. Sollaccio reviews your symptoms, examines your hand and arm, and checks sensation and strength. Nerve conduction studies and EMG tests, which measure how well nerves and muscles are working, can confirm the diagnosis and show how severe the compression is.
Why early treatment matters. Mild nerve compression often responds well to splinting, activity changes, and other nonsurgical care. But long-standing compression can lead to permanent numbness or muscle loss. Seeing a specialist when symptoms first become persistent gives you the most treatment options and the best chance of full recovery.
When to call 911. Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, along with confusion, trouble speaking, vision changes, or loss of balance, can be signs of a stroke. Call 911 immediately. You should also seek emergency care for numbness after a serious injury when fingers look pale or blue, or feel cold.
