If you have carpal tunnel syndrome, the first and most effective thing you can do at home is wear a wrist splint at night. Beyond that, a combination of workspace changes, anti-inflammatory habits, and knowing when to escalate to injections or surgery can make a significant difference. Most people start with conservative measures and only need surgery if symptoms persist or worsen.
Start With a Night Splint
A wrist splint worn during sleep is the simplest, most well-supported starting point. Your wrist naturally bends while you sleep, which compresses the median nerve running through the carpal tunnel. A splint holds your wrist in a neutral position and takes that pressure off.
For this to work, you need to wear it every night for at least eight weeks. That timeline matters because many people give up after a week or two without noticing improvement. The splint should fit snugly enough to hold your wrist straight but not so tight that it causes swelling or cuts off circulation. Importantly, splints are for nighttime only. Wearing one during the day can actually weaken your wrist and forearm muscles over time, making things worse.
You can find wrist splints at most pharmacies without a prescription. Look for one labeled for carpal tunnel specifically, as it will hold your wrist at a neutral angle rather than flexing it in either direction.
Fix Your Workstation Setup
If you spend hours at a keyboard, your desk setup may be contributing to your symptoms. The goal is to keep your wrists flat and in line with your forearms, avoiding any upward or downward bend at the wrist joint.
Set your keyboard and mouse at the same height, level with your elbows. Your chair height should allow your elbows to rest at keyboard level with your arms bent at roughly 95 to 100 degrees. A padded palm rest (firm, not squishy) can help guide your wrists into the right position while typing. If you’re using a laptop on a table that’s too high or too low, even the best posture habits won’t help much.
Beyond the physical setup, take breaks. Even brief pauses every 20 to 30 minutes to shake out your hands and stretch your fingers can reduce the cumulative pressure on the nerve. Some people find that switching to a split keyboard or a vertical mouse helps, though the evidence for specific products is less clear than for overall positioning.
Reduce Inflammation Through Diet
What you eat can influence how much inflammation builds up around the carpal tunnel. A diet rich in fruits, vegetables, whole grains, and healthy fats, along the lines of a Mediterranean diet, has been shown to reduce systemic inflammation. Foods high in omega-3 fatty acids like fatty fish, flaxseed, and walnuts may be particularly helpful.
On the flip side, processed foods can increase inflammatory proteins that are directly linked to carpal tunnel syndrome. Fried and salty foods contribute to both inflammation and fluid retention, and that extra swelling in the wrist tissues puts more pressure on the nerve. Alcohol also raises inflammation levels. You don’t need a perfect diet, but shifting the balance toward whole foods and away from heavily processed ones can make a noticeable difference, especially if you’re also carrying extra weight. Excess body weight is one of the strongest risk factors for carpal tunnel syndrome, and even modest weight loss can reduce pressure in the carpal tunnel.
Steroid Injections for Short-Term Relief
If splinting and lifestyle changes aren’t enough, a corticosteroid injection into the carpal tunnel can provide meaningful relief. The injection reduces swelling around the nerve and can ease symptoms quickly. However, the relief tends to be temporary. Clinical evidence shows strong effectiveness in the short term (up to about 10 weeks), but long-term benefits are not well supported. Many people find symptoms return after a few months.
Injections are most useful as a bridge: they can confirm the diagnosis (if the injection helps, it’s almost certainly carpal tunnel), buy you time while you try other strategies, or provide relief during a temporary flare. Most doctors limit the number of injections to avoid tissue damage in the wrist.
When Surgery Makes Sense
Surgery becomes the right move when you have numbness that doesn’t go away, weakness in your hand (particularly difficulty gripping or pinching), or visible muscle wasting at the base of your thumb. These signs indicate the nerve is being damaged, not just irritated, and waiting longer can lead to permanent loss of hand function.
Carpal tunnel release surgery is one of the most common hand procedures performed. The surgeon cuts the ligament that forms the roof of the carpal tunnel, permanently relieving pressure on the nerve. There are two approaches: open surgery (a small incision in the palm) and endoscopic surgery (one or two tiny incisions using a camera). Endoscopic surgery generally involves less pain, faster recovery, and an earlier return to work and sports.
Recovery is faster than most people expect. You can typically return to desk work or light activities within one to two days. More physically demanding jobs may require a few weeks, and strenuous activities like sports or heavy lifting usually take four to six weeks. Most patients can handle basic daily tasks like eating, dressing, and using a phone within a few days of the procedure.
Carpal Tunnel During Pregnancy
Pregnancy-related carpal tunnel is common and has its own trajectory. Fluid retention during pregnancy increases pressure in the carpal tunnel, and symptoms often appear in the second or third trimester. The good news is that 85% of women see their symptoms resolve within six weeks after delivery as fluid levels return to normal.
For the roughly 15% who still have symptoms a month after delivery, the outlook is less encouraging. Women whose symptoms haven’t resolved by three months postpartum tend to see them persist and even worsen over time, so it’s worth pursuing treatment rather than continuing to wait it out. During pregnancy itself, night splinting is the safest and most common approach since steroid injections and surgery are typically deferred until after delivery when possible.
How Carpal Tunnel Is Diagnosed
If you’re not sure whether your symptoms are actually carpal tunnel, a doctor can usually figure it out without advanced testing. The American Academy of Orthopaedic Surgeons now highlights a clinical assessment tool called the CTS-6, which combines six physical exam findings and symptom characteristics to diagnose carpal tunnel syndrome with high accuracy. For many patients, this replaces the need for nerve conduction studies or ultrasound.
Nerve conduction studies (where small electrical impulses measure how fast signals travel through the median nerve) and ultrasound are still used when the clinical picture is unclear. MRI, on the other hand, is not recommended for diagnosing carpal tunnel. It has low specificity, meaning it produces too many false positives to be reliable for this condition. If your symptoms include numbness and tingling in your thumb, index, and middle fingers that’s worse at night and improves when you shake your hand out, the pattern alone is strongly suggestive of carpal tunnel syndrome.
