You suddenly have numbness, tingling, or feel as if your hands or feet have been “switched off”. Numbness in the hands and feet may result from pressure on a nerve, or it may change or decrease, but if it is persistent, recurrent, or spreading, it could indicate nerve damage, circulatory issues, or another underlying condition.
This may be referred to as “pins and needles” or as a feeling of the fingers, toes, palms, or soles tingling or burning, weakness, or a “dead” feeling. It may be temporary (such as when resting on your arm) or persistent, and must be medically evaluated.
What is Numbness in Hands and Feet?
Numbness in hands while sleeping can be associated with carpal tunnel or cubital tunnel or pressure on the nerves in the neck. Nerves may also be irritated over time by repetitive hand movements (typing, handling tools).
Numbness in hands and feet is a decrease in sensation in hands and feet or low sensitivity in arms and around your legs. It is commonly seen with a feeling of tingling in the same areas. What is the cause? The cause is not determined; it can be pressure, a medical condition, or underlying issues.
At what time do hands and feet go limp?
The numbness in hands and feet is mostly caused by pressure or irritation, or can even be caused by injury to nerves. Another main reason for this is diabetes, which affects the outside of your brain and spinal cord (THE PERIPHERAL NERVES).
Common causes include:
- High blood sugar levels over time can cause damage to nerves.
- Carpal tunnel syndrome — a compression of a nerve at the wrist.
- A nerve that has become trapped in the neck or lower back.
- The deficiency is caused by vitamins like vitamin B12, Vitamin B1, Vitamin B6, folate, copper, or vitamin E.
- Diseases in the kidney, nerves are the results of excess alcohol or infections caused by medication.
Why Do Numbness and Tingling Occur in Hands and Feet When I Sleep?
The numbness of hands and feet in sleep is constant due to the pressure on the nerve while you sleep. The sleeping position affects this numbness, as blood circulation decreases when you sleep longer in one position. If your wrist, elbow, neck, or spine is not supported, it could also be caused by this.
Possible triggers include:
- Lying on your arm or hand.
- Keeping your wrist bent for a long time.
- An unsupported neck or back pillow/mattress.
Its symptoms can interrupt sleep with numbness in the hand, can make it difficult to move or use your hand and can cause discomfort, and is called carpal tunnel syndrome.
Damage to nerves that can be more painful at night, caused by diabetes.
What Causes Numbness in Hands and Feet During Sleep?
Numbness in hands while sleeping can be associated with carpal tunnel or cubital tunnel or pressure on the nerves in the neck. Nerves may also be irritated over time by repetitive hand movements (typing, handling tools).
Waking you up frequently, impacting your grip or with pain — see an evaluation. With early treatment, more chronic symptoms can be avoided.
What causes of numbness in hands and feet?
If numbness in both hands and feet, it could indicate more serious nerve issues than it is just pressure on one nerve. Both sides of the body may be involved in peripheral neuropathy, vitamin deficiency, thyroid disease, and some autoimmune disorders.
Possible causes include:
- Diabetes or metabolic syndrome.
- Vitamin B12 deficiency.
- Underactive thyroid.
- Alcohol-related nerve damage.
- Multiple sclerosis or other neurological diseases.
- Medications that cause side effects.
Conditions Causing Numbness
Can low blood pressure cause numbness in hands and feet?
Sometimes Yes, If your blood drops suddenly, it might have an effect on blood flow in your hands and legs which can result in numbness and tingling sensation around your hands and feet.
But low blood pressure is not your main concern, as the common reasons for numbness are nerve damage and compression, diabetes, and vitamin deficiency.
Can high cholesterol cause numbness in hands and feet?
Can high cholesterol cause numbness in hands and feet? The answer is no; high cholesterol does not really lead to numbness in those areas. But with time, if you are careless, then it can show narrowing and blockage of the blood vessels and also reduced blood flow.
What causes numbness in hands and feet during pregnancy?
Pregnancy is delicate, and even slight hormonal changes can cause this numbness. Pressure on nerves or fluid retention are some causes of tingling or numbness in hands and legs.
The majority of numbness following pregnancy clears up after birth. If there is sudden weakness, a lot of swelling, and severe headache or one-sided numbness, then medical help should be sought immediately.
Frequently Asked Questions
Q1. What is the most common cause of numbness in hands & feet?
It’s most commonly caused by peripheral neuropathy, which is frequently associated with diabetes. Other causes are nerve compression, deficiency of vitamin B12, thyroid disorders, damage to the nerves from alcohol and some drugs.
Q2. How to get rid of numbness in hands and feet?
The treatment for numbness in hands and feet will vary based on the cause. Changing position and moving the affected limb lightly will suffice to relieve temporary numbness caused by pressure.
Q3. Does high levels of cholesterol lead to numbness in hands and feet?
High cholesterol does not lead to numbness. But, with the passage of time, it can result in narrowing and blockage of the blood vessels and reduced blood flow to the extremities.
Q4. At what point do I have to get medical help?
If numbness in hands and feet is not apparent, if it returns, if it lasts or if both hands and feet are affected, seek medical attention. Proper evaluation is important – some types of nerve damage can be treated before they become serious.
If numbness: GET EMERGENCY ASSISTANCE.
- Starts suddenly.
- Follows a head, neck or back injury.
- Comes with weakness, paralysis or loss of movement.
- Combines with problems with comprehension, speech, vision, or a really bad headache.
- Comes with loss of bladder or bowel control.
Conclusion
Tingling numbness in hands and feet can be caused by different reasons like pressure, nerves, or even your sleeping positions, but if it is constant, or extends or impairs your grip, balance, or even your sleep, then it is a problem. Most of it is temporary, but if it isn’t, then it can be nerve damage, circulatory problems, or an underlying cause. Early assessments can preserve your nerves and avoid further issues.
