A foot that's fallen asleep is not normally something to worry about. But you may want to seek medical help if it's long-lasting, happens often, or is coupled with other symptoms or concerns.
Tingling may be caused by pressure on the nerves when you've been in one position for too long. The feeling should go away when you move. However, tingling in the feet may be persistent. If the “pins and needles” feeling continues for a long period of time or is accompanied by pain, see your doctor.
Depending on the cause, the loss of sensation can disappear quickly, such as numbness after sitting for a long time that will fade away once you move your legs and feet around. Chronic numbness in the feet generally indicates some level of damage to the nerves.
Home remedies that may help to relieve uncomfortable numbness in the legs and feet include:
- Rest. Many of the conditions that cause leg and foot numbness, such as nerve pressure, improve with rest.
- Ice.
- Heat.
- Massage.
- Exercise.
- Supportive devices.
- Epsom salt baths.
- Mental techniques and stress reduction.
Tingling or numbness in fingers or toes or a feel of body parts “falling asleep” Lack of – or reduced – sweating, even in strenuous situations.
Nerve issues are often a side effect of some prescription drugs. Medications for cancer (chemotherapy), HIV or AIDS, high blood pressure, tuberculosis, and certain infections can cause weakness or numbness in your hands and feet.
Someone who falls asleep on a limb is unlikely to do major damage to the nerves, Dyck says. But there are some cases when compressed nerves can become a greater problem. One such case is called "Saturday night palsy," when a person falls asleep compressing a nerve while drunk.
With intermuscular injuries, most athletes will be able to return to sport within a few days, but if the injury is severe it might take up to 2-3 weeks. The time for a return to sport is longer with intramuscular injuries, but very few athletes will develop any long lasting problems.
“When you bear down to poop, you raise the pressure in your spinal column, technically called the intrathecal pressure. Sometimes that rise in pressure will cause the discs in your spine to move against the nerves where they exit the spine and cause numbness, weakness, and a generally weird feeling down the legs.
“It is possible to damage your nerves, but probably not through occasionally sleeping funny,†says Kleitman. In experiments to study paresthesia, patients have kept blood pressure cuffs on their arms for over an hour without any permanent ill effect, says Yale's LaMotte.
A dead leg is caused by a direct blow to the thigh. This can occur by being struck by an object or by colliding with another person. The blow crushes the quadriceps muscle against the underlying bone. This damages the muscle fibres and blood vessels of the quadriceps, causing bleeding and swelling.
Occasional bouts of pins and needles usually aren't a cause for concern. But, if you've tried home remedies and your symptoms are severe or long-lasting, you should see your doctor. Chronic paresthesia could be triggered by nerve, spinal cord, or brain damage.
Keep your feet roughly shoulder-width apart and let your arms hang naturally at the sides of your body. For a good night's rest, finding the right mattress for your body is crucial. A firm mattress is recommended, but some find softer mattresses reduce back pain. Also, use a pillow while sleeping.

Vitamin deficiencies.You need vitamins E, B1, B6, B12, and niacin for healthy nerves. A B12 deficiency, for example, can lead to pernicious anemia, an important cause of peripheral neuropathy. But too much B6 also can cause tingling in the hands and feet.
Try a new sleeping position, particularly on your side. Avoid laying on your arms under your pillow, which can compress nerves. Make sure your wrists remain unflexed, since flexing can lead to tingling. If you often sleep on your back with your arms overhead, try keeping them next to you to reduce nerve pinching.
Side sleeping best practices
- Lie down on a medium-firm mattress, using one firm pillow underneath your head.
- Shift over to your left side first.
- Keep your arms and hands below your face and neck, preferably parallel to the sides.
- Put a firm pillow between your knees (especially if you have low back pain).
Numbness is most commonly associated with some type of nerve damage, irritation, or compression. When numbness occurs without other symptoms, it doesn't typically represent a medical emergency. However, numbness can be a symptom of a serious condition if it occurs alongside symptoms such as: numbness on one side.
Other symptoms of vitamin D deficiency include depression and pins and needles, tingling or burning sensation in the hands, feet and toes.
When we feel a body part fall asleep, it may be paresthesia. Unlike commonly thought, the situation has less to do with blood circulation and more to do with nerves. Paresthesia is an abnormal sensation felt in your body due to compression or irritation of nerves.
Numbness or tinglingHowever, if this numbness continues, comes on suddenly, or only happens on one side of the body, it may be time to see a neurologist. Numbness or tingling symptoms like those described can also be signs of a stroke, in which case you need to get help very quickly.
Anxiety can cause facial numbness and a tingling sensation. These symptoms of anxiety may trigger fears of a serious medical problem, such as a stroke or head injury. Many different conditions can cause numbness, but tingling and numbness are among the most common anxiety symptoms, especially during a panic attack .
Sleeping on your arm restricts the blood flow and can cause a numb sensation in the arm and hand. Typically this is shortlived and a simple message can wake it up.
The most common reason for getting a numb hand or arm is sitting or sleeping in the same position for a long time. That can put pressure on your nerves and cut off blood flow, which brings on short-term numbness.
Tingling hands or feet
Vitamin B-12 deficiency may cause “pins and needles†in the hands or feet. This symptom occurs because the vitamin plays a crucial role in the nervous system, and its absence can cause people to develop nerve conduction problems or nerve damage.When nerves do not work properly, this is be called neuropathy. It can cause a number of different symptoms including numbness, tingling, pins and needles, feeling like the foot is covered in leather, very hot or cold sensations, shooting pain and burning.
Discomfort may not start or stop in your chest. Pain, pressure, tingling or numbness in your back, neck, jaw, arms and other areas nearby is also possible. Chest or upper body pain or pressure may not be the only thing you feel. You could also feel dizzy or breathless – which we talk more about below.
Anxiety and stress do affect the body in many different ways. A few of the most obvious symptoms of stress include numbness, burning, tingling, and pain or discomfort when moving. These symptoms are very similar to what you might feel with neuropathy.
