CARPAL TUNNEL SYNDROME IN PREGNANCY · Las Vegas, NV
Numb hands in pregnancy don’t always mean waiting it out
If your hands go numb and burn through the night, and you’ve been told to wear a brace, take Tylenol, and wait until you deliver, that’s the standard advice. But it isn’t the only option, and for some pregnancies, it isn’t the right one.
There’s a non-surgical treatment we can do at any stage of pregnancy using 5% dextrose, a.k.a. sugar water, placed around the median nerve under ultrasound guidance. Whether it fits your case depends on the diagnosis, which is what the consultation is for.

You’re not imagining it
Pregnant women are routinely told that the only thing to do about any ache or pain is to get over it, wait until delivery, or take some Tylenol. Meanwhile, the hands are numb, tingling, and burning badly enough to prevent sleep, the brace helps (or it doesn’t), and depending on when the symptoms started, she may be looking at months of this. Her back already hurts. She may be dealing with morning sickness. Nobody seems to have anything else to offer. That gap is what OASIS is here to fill.
Why “wait until delivery” is sometimes right and sometimes isn’t
Carpal tunnel syndrome is compression of the median nerve inside the carpal tunnel of the wrist. Pregnancy causes fluid shifts and fluid retention in unexpected places, which is why so many women report swollen feet and legs in the third trimester, and that same swelling can happen inside the carpal tunnel. If a nerve stays compressed and irritated for long enough, some of the damage moves from reversible to irreversible, and some symptoms won’t resolve after delivery. Carpal tunnel syndrome isn’t life-threatening, but that doesn’t make it a benign condition.
The timing matters more than the advice suggests. Most pregnancy-related carpal tunnel syndrome starts in the third trimester, and if it starts then and is manageable, you’re nearly there, and nothing bad is likely to happen while you wait. If it started in the first or second trimester and it’s severe or getting worse, waiting is where you start playing with the possibility of permanent nerve damage.
How common is this? Reported rates run from about 7% to 43% of pregnancies when the diagnosis is confirmed with nerve conduction testing, and from 31% to 62% when it’s diagnosed on symptoms alone.¹ That spread mostly measures how the counting was done rather than how common the condition is. The same review found symptoms still present in more than half of affected women a year after delivery, and in about 30% at three years.¹
One thing that doesn’t matter: whether the carpal tunnel syndrome started with the pregnancy or was already there and got worse. If you have numbness, tingling, or burning in the thumb, index, and middle finger, and a swollen median nerve in the carpal tunnel, the treatment is the same either way.
How we figure out what’s actually wrong
Numb, tingling hands don’t always mean carpal tunnel syndrome. The median nerve can be compressed anywhere along its course, from the neck through the armpit, upper arm, elbow, and forearm to the wrist. A treatment aimed at the wrist won’t help a nerve that’s pinched somewhere else, which is why a proper diagnosis is so important. Every consultation at OASIS includes:
-
A real medical interview — what’s numb, when it started, what makes it better or worse, and what’s going on in the rest of your body.
-
A full physical examination — including the side that doesn’t hurt, because comparison is part of the answer.
-
Musculoskeletal ultrasound of the nerve along its entire course — so we can see every point where it’s being entrapped, not just the one everybody assumes.
Scanning the whole course matters more than it sounds. If the nerve is being compressed in two places, say the carpal tunnel and the elbow, that’s double crush syndrome, and treating only the wrist means you won’t get better. If we identify both targets on the ultrasound, both get treated.
Once we know what’s actually wrong, we’ll tell you honestly whether it’s something we treat or something better handled elsewhere.
What ultrasound-guided hydrodissection actually involves
If the median nerve at the wrist is confirmed as the source of your symptoms during the consultation, you may be a candidate for hydrodissection.
We use 5% dextrose and nothing else: no lidocaine and no steroids, to keep fetal exposure to a minimum. Dextrose is sugar water, and it’s the same substance given to newborns in intensive care, by mouth and by IV, when their blood sugar is too low. It’s as basic as medicine gets.
Up to roughly 10 mL goes in under ultrasound guidance, above and below the median nerve at the level of the carpal tunnel, separating the nerve from the tissue binding it. The effect is both mechanical and chemical: the physical separation produces much of the benefit, and the dextrose calms down inflammation around the nerve.
You can be positioned whichever way is comfortable, and late in a pregnancy that matters. Your arm can rest on a desk with Dr. Kiok sitting across from you, or you can lie flat with your arm at your side, or stay semi-reclined like a beach chair, palm up.
The goal isn’t only to make the symptoms less miserable; it’s to prevent permanent nerve damage. Pregnancy-related carpal tunnel syndrome can be more severe than the kind that comes from poor ergonomics. There’s simply too much fluid in too little space.
To gauge the effectiveness of the initial treatment, we measure the cross-section of the median nerve before treatment and again a week or two afterward. If the effect isn't enough, the procedure can safely be repeated up to two more times (three in total).
Where this is unlikely to help: numbness and tingling that’s actually coming from your neck, such as a cervical radiculopathy. If the nerve is entrapped in the forearm as well as the wrist, that’s a different situation, and we can hydrodissect both.

After delivery
Postpartum cases tend to be the more severe ones, and there’s a reason for that.
Too much fluid in the carpal tunnel compresses the median nerve. A compressed nerve swells, and in a space that can’t expand, a swollen nerve leaves even less room, which compresses it further. That’s a self-sustaining cycle. Dr. Kiok explains it to patients this way: bite your cheek, and it swells; once it’s swollen, you bite it again, and then it’s puffier still, so you keep biting it.
The same thing can happen inside the carpal tunnel. By the time you deliver, the fluid shifts may be gone, but the nerve is irritated enough to be sustaining the problem on its own.
After delivery, the options do widen. Corticosteroid injection becomes a more reasonable choice, and the risks of surgery and anesthesia are more acceptable than they were during pregnancy. Hydrodissection is still what Dr. Kiok would offer first, beyond bracing, to almost anyone with carpal tunnel syndrome.
The number to remember: if you’re a month past delivery and your symptoms haven’t improved at all, get it evaluated. You may be one of the women whose carpal tunnel syndrome is now sustaining itself.
How hydrodissection compares to a brace, Tylenol, cortisone, or surgery
Hydrodissection vs. a wrist brace. A stiff brace keeps the wrist from bending inward, which is what drives pressure up inside the carpal tunnel. For mild cases, it’s sometimes enough, and there’s no real risk to it beyond the inconvenience of wearing it consistently every night for weeks. For the women it doesn’t work for, there hasn’t been a next step.
Hydrodissection vs. Tylenol. For most pregnant patients, Tylenol is the entire menu. Very few treatments are ever trialled in pregnancy, so very little gets approved for it, and the result is a population with real symptoms and almost nothing available to treat them. Tylenol is a “Band-Aid” for pain, and not a very good one for neuropathic pain: the type that comes from damaged nerves.
Hydrodissection vs. physical or occupational therapy. PT/OT won’t necessarily harm you, but it’s hard to say how helpful they could be for this particular condition. Nerve gliding exercises have a place in treating nerve disorders generally, but carpal tunnel syndrome is a problem of too much pressure in too little space, and therapy can’t create space.
Hydrodissection vs. cortisone. A corticosteroid injection into the carpal tunnel is a standard option for patients who aren’t pregnant. During pregnancy, there are concerns about maternal corticosteroid exposure affecting fetal development, and most women are understandably reluctant to expose the baby to anything that might carry a risk.
Hydrodissection vs. surgery. Carpal tunnel release is offered during pregnancy as a last resort, usually when the nerve damage looks severe, and the onset was early, such as the first trimester. The reasoning is sound: left untreated that long, the damage becomes permanent, so the risk of waiting outweighs the risk of operating.

Ready for an actual answer?
If your hands have been numb for months, the brace isn’t doing anything, and you’ve been told there’s nothing to do but wait until you deliver, book a consultation.
If you’re not sure whether you’d be a candidate, that’s exactly what the consultation is set up to figure out.
