Your hands are involved in nearly everything you do. When something goes wrong with them, whether it is numbness, tingling or a finger that locks in place, it can affect every aspect of daily life. Because these symptoms can start small and gradually become more disruptive, understanding what may be happening is the first step toward getting relief. Dr. Ayesha Punjabi, a plastic and reconstructive surgeon at Southwest General Health Center, breaks down two of the most common hand conditions she treats and what patients can do about them.
Carpal Tunnel Syndrome
Carpal tunnel syndrome occurs when the median nerve, one of the major nerves that travels through the arm and into the hand, becomes compressed at the wrist. The nerve passes through a narrow tunnel beneath a ligament, and when inflammation builds up in that space, pressure on the nerve increases. The result is numbness and tingling in the thumb, index and middle fingers—often worse in the morning.
"Patients describe waking up and having to shake their hand to get the ‘pins and needles’ out," Dr. Punjabi states. Over time, if left untreated, the condition can progress to muscle weakness, particularly in the muscles that help the thumb meet the other fingers. Since the thumb is so central to hand function, that progression is something to take seriously.
Repetitive motion jobs (e.g., typing, gripping, manufacturing) can increase the risk, especially when poor wrist positioning adds pressure to the tunnel.
Trigger Finger
Trigger finger is a different condition but equally disruptive. It occurs when the tendon that curls a finger becomes inflamed at the entrance of the sheath it travels through. Instead of gliding smoothly, the tendon gets stuck. "The finger can lock in a flexed position, and patients have to manually pull the finger extended," Dr. Punjabi explains.
Like carpal tunnel, trigger finger is related to inflammation and use. However, Dr. Punjabi is quick to reassure patients: "People should live their lives. None of this should make people hesitant to use their hands."
Treatment Options for Both
Before surgery is considered, there are steps patients can try at home. A wrist brace worn during sleep can relieve overnight pressure on the median nerve. A small finger brace, or even stacked Band-Aids, can prevent a trigger finger from curling inward overnight.
When those measures are not enough, steroid injections are the next step. For trigger finger, about half of the cases can be resolved with a single injection in the clinic. Surgery, when needed, is straightforward for both conditions.
Carpal tunnel release involves a small incision near the wrist and takes about ten minutes. Trigger finger release takes roughly seven minutes. Both are outpatient procedures, and patients can even remain awake if they prefer. "On the scale of surgeries, these are very well-tolerated," Dr. Punjabi emphasizes.
Recovery allows for gentle activities such as typing and writing within days. Heavy lifting should be avoided for at least one month.
When to Seek Help
Both conditions described above share a common threshold for when it is time to act. "With the hand, if something is interfering with your day-to-day life, it's a problem," Dr. Punjabi cautions. Whether it affects work, hobbies or simple daily tasks, that is the signal to see a specialist.
