You may experience a tingling sensation or numbness during pregnancy, which is also described as a ‘pins-and-needles’ sensation. It usually affects the hands, fingers, feet, or legs. Further, the stretching of your belly as your pregnancy progresses can sometimes cause numbness in that region too. Most pregnant women experience these symptoms at some point during their pregnancy.
Read this post to learn more about numbness during pregnancy, including whether it is normal, its symptoms, the possible causes, how to treat and manage it, how to prevent it, and whether numbness is an early sign of pregnancy.
Is Numbness Normal In Pregnancy?
Numbness is usually normal, as the uterus grows and presses against the nerves supplying the legs. You may also experience tingling in your hands and fingers, especially after you wake up in the morning. These sensations are likely to go away after delivery (1).
If you experience other symptoms, such as abdominal contractions, pain, bleeding, blurry vision, or swelling, along with numbness, consult your doctor.
Symptoms Of Numbness During Pregnancy
In addition to numbness in your fingers, hands, legs, and feet, you are likely to experience other symptoms, such as:
- Tickling, burning, itching, and crawling sensation under the skin
- Radiating pain
- Slurred speech
- Loss of bladder or bowel control (2)
These symptoms may keep you awake at night. They usually occur in the middle or end of your pregnancy, along with weight gain and water retention.
Possible Causes Of Numbness and Tingling In Pregnancy
The common causes of numbness or tingling sensation include:
1. Hormonal changes, especially an increase in the levels of hormone, such as relaxin, stretches the ligaments with growing pregnancy, may shift your center of gravity and affect your posture. This could lead to nerve compression (or pinching), resulting in pain and burning sensation around the thighs, legs, back, and buttocks (3).
2. Bodily changes, Growth of the uterus could put pressure on the muscles, nerves, and ligaments, causing numbness and tingling sensations (1).
3. Water retention that occurs in the second and third trimesters could cause swelling of hands and feet (4). TAlso called edema, this swelling may contribute to numbness in the extremities and may put pressure or cause pain in the surrounding area (5).
4. Numbness in hands and fingers may develop due to carpal tunnel syndrome (CTS) that occurs when pressure is built upon the median nerve of the wrist due to water retention. It is one of the common complications in pregnancy, and one study reports its frequency as high as 62%. You may experience symptoms such as:
- Numbness or tingling in the thumb, index, middle finger, or radial half of the hand
- Dysesthetic wrist pain (pain due to burning sensation)
- Loss of grip strength and dexterity (difficulty grasping objects)
- Radiating pain in forearm and shoulder
These symptoms are likely to be worse at night and aggravate during forceful activity and change in wrist position (6).
Numbness in the legs (paresthesia), back, and rear could be caused due to two conditions – sciatica and meralgia paresthetica.
5. Sciatica, which is caused by pressure on the sciatic nerve, affects around 30% of pregnant women (7). It may occur from weight gain and water retention that put extra pressure over the spine and sciatic nerve. Along with the numbness and tingling sensations, you may experience other symptoms, such as pain, burning, and muscle weakness in your leg, lower back, buttocks, and hips (8).
6. Meralgia paresthetica occurs from the compression of the lateral femoral cutaneous nerve (LFCN) that supplies sensation to the lateral aspect (front and side) of the thigh. It is likely to cause numbness, tingling, or burning sensation in the thigh. The symptoms may be confined to one leg and could intensify with standing or walking (9).
Numbness and tingling could also be symptoms of certain pregnancy-related conditions. Therefore, check with your doctor to figure out what exactly is causing numbness.
7. Iron-deficiency anemia, affecting 36.5% of pregnant women globally according to WHO, can lead to restless leg syndrome, which is a neurological disorder where you may suffer from the irresistible urge to move your legs. You will experience tingling or a crawling sensation in the legs (10).
8. Vitamin B12 deficiency might result in nerve damage or neuropathy that could cause numbness or tingling of fingers and toes, which in most circumstances is temporary and can be treated. Other symptoms include muscle weakness, memory loss, impaired balance, and behavioral changes (11).
9. Pre-eclampsia leads to the swelling of legs, hands, face, and sometimes the entire body. It could be a potential cause for numbness, and if combined with headache, visual changes, breathing difficulty, nausea, or vomiting, it needs medical attention (12).
10. Gestational diabetes may cause pain, numbness, or tingling in the hands or feet. It is accompanied by frequent urination, fatigue, blurry vision, frequent hunger, and excessive thirst and may be associated with gestational hypertension It could raise the risk of type 2 diabetes later in life, and therefore needs proper management (13).

Treatment For Numbness In Pregnancy
Treatment for numbness or tingling sensation depends on its cause. Your doctor might suggest non-steroidal anti-inflammatory medicines to treat the pain associated with numbness (16).
Can You Prevent Numbness?
You may not be able to prevent numbness but can reduce its chances by making some changes to your diet and lifestyle.
- Include a healthy and balanced diet to gain healthy pregnancy weight. Cut down on salt, sugar, and fats, and drink enough water. Take the necessary supplements by checking with your doctor.
- Stay away from alcohol as the toxins in it may lead to nerve damage and cause numbness.
- Minimize the time spent on activities such as typing, knitting, or sewing, especially if you are at risk of carpal tunnel syndrome.
- Get a supportive maternity bra that may take off the weight from your breastbone and rib cage that may otherwise apply pressure on the median nerve.
- A correct posture is important while sitting, standing, or sleeping.
- Use well-fitting, non-skid shoes that have soft soles.
Is Numbness A Sign Of Early Pregnancy?
Numbness is not likely to be a sign of pregnancy unless it is caused by carpal tunnel syndrome (common in pregnancy). It occurs when there is water buildup in the tissues of the wrist, which may squeeze the median nerve running down to hands and fingers. This could, therefore, cause numbness and a tingling sensation (6).
Frequently Asked Questions
1. Can numbness during pregnancy affect my baby?
Numbness due to bodily changes, water retention, or hormonal changes during pregnancy is not likely to affect the baby. However, if caused by nutrient deficiencies or conditions such as preeclampsia, it may harm the fetus.
2. Can numbness during pregnancy be a sign of a pinched nerve?
A pinched or compressed nerve may cause pain, numbness, and tingling. The extra tissues that your body has during pregnancy may create pressure on the nerves, leading to numbness (19).
3. Can numbness during pregnancy be a sign of a blood clot?
Yes. Blood clots (thrombosis) may cause numbness as a symptom. Deep vein thrombosis (DVT) may occur during pregnancy and may have symptoms such as pain in one leg (calf or inner thigh), swelling in the arm or leg, and numbness or weakness on one side of the body (20).
Numbness during pregnancy could be due to several factors, and it usually resolves on its own after childbirth. You could try a calming foot bath or a massage to calm your legs.
