Muscle soreness can be caused by many factors, and it can sometimes lead to a pins-and-needles sensation. This feeling is medically referred to as paresthesia, characterised by a tingling, prickling, or numbness sensation. Paresthesia is typically caused by pressure on a nerve or restricted blood flow, often due to body positioning, such as sitting or sleeping on a limb. While usually harmless and temporary, persistent or frequent pins and needles can indicate a more serious underlying condition, such as nerve damage, carpal tunnel syndrome, or peripheral neuropathy. It is recommended to seek medical advice if pins and needles are accompanied by symptoms like muscle weakness or if they persist after changing posture or limb position.

What You'll Learn
Paresthesia and nerve irritation
Paresthesia is the feeling of pins and needles that occurs when you change position and release the pressure on the nerve or blood vessels in that body part. It can also be caused by bumping into something, which can cause a sharp, shock-like feeling of tingling or pain. This is known as "hitting your funny bone".
Paresthesia can also be caused by certain toxins and poisons, such as arsenic poisoning, carbon monoxide poisoning, chemotherapy, and lead poisoning. Additionally, nerve compression syndromes, such as carpal tunnel syndrome, can cause paresthesia. Carpal tunnel syndrome occurs when the main nerve servicing the hand is irritated or compressed due to inflamed and swollen tendon membranes reducing the amount of room inside the wrist.
Peripheral neuropathy is a term used to describe any condition affecting the nerves outside the brain or spinal cord. It can be caused by trauma, infections, or inherited conditions. Peripheral neuropathy can affect anyone, regardless of age, sex, or ethnicity, but some people are at greater risk for specific types. For example, people with diabetes are at risk of developing diabetic neuropathy, which can cause paresthesia.
Treatment for paresthesia depends on the underlying cause. For example, carpal tunnel syndrome may be treated with rest, splinting, and anti-inflammatory medications. In some cases, surgery may be required to ease the pressure on the nerve and allow full functioning to resume. It is important to see a doctor if you experience frequent or persistent bouts of pins and needles, as it could indicate nerve damage.

Carpal tunnel syndrome
Experiencing a pins-and-needles sensation is usually not a cause for concern. This sensation is medically referred to as paresthesia, which means ""abnormal feeling", indicating a change in nerve function. It is often caused by leaning or lying awkwardly on an arm or a leg, which either presses against the nerves or reduces blood supply to the local area. Changing positions usually quickly restores normal feeling.
However, pins and needles can sometimes be a symptom of an underlying condition, such as carpal tunnel syndrome. Carpal tunnel syndrome is an extremely common wrist issue that affects around 3 out of every 1,000 people in the US each year. It occurs when something irritates or puts extra pressure on the median nerve, which runs through the carpal tunnel in the wrist. The median nerve helps you move your forearm and gives feeling to most of your fingers and hands.
The carpal tunnel is a narrow passageway in the wrist, about an inch wide, with a strong band of connective tissue called the transverse carpal ligament forming its roof. The tunnel has little capacity to stretch or increase in size. Carpal tunnel syndrome is caused by inflammation and swelling of the tendon membranes, which reduces the amount of room inside the wrist and irritates or compresses the nerve. This can lead to symptoms such as wrist pain, tingling, numbness, and weakness. The symptoms usually first appear at night and may get worse over time, eventually affecting daily activities such as typing, writing, or using tools.
If you are experiencing symptoms of carpal tunnel syndrome, it is important to seek treatment promptly to prevent permanent nerve damage. Treatment options include rest, wearing a splint, physical therapy, and in some cases, surgery to take pressure off the median nerve.

Sciatica
Experiencing a pins-and-needles sensation is usually not a cause for concern. This happens when the blood supply to the nerves is cut off, often when you sit or sleep on a part of your body. It can also be caused by leaning or lying awkwardly on an arm or leg, which either presses against the nerves or reduces the blood supply to the local area. Changing positions usually quickly restores normal feeling.
However, pins and needles can sometimes be a sign of nerve or artery damage. It can also be caused by certain supplements, such as beta-alanine and vitamin B6. If your pins and needles feeling doesn’t improve with a change in your posture or limb position, you should see a doctor.

Underlying health issues
While pins and needles are usually harmless and go away on their own, they can sometimes be caused by underlying health issues. This is known as paresthesia, which can be transient (short-lived) or persistent (long-lasting). Transient paresthesia is very common and usually happens due to body positioning that puts pressure on a nerve or limits blood flow. This can be resolved by simply changing positions or moving around.
However, if the pins and needles sensation persists or occurs frequently, it may be a symptom of an underlying medical condition. Persistent paresthesia is often caused by issues that may require medical attention. For example, carpal tunnel syndrome or cubital tunnel syndrome can cause long-lasting paresthesia. Additionally, lack of circulation or nerve damage can lead to persistent paresthesia and may be more serious.
Underlying conditions such as diabetes, vitamin deficiency, or alcohol use disorder can contribute to peripheral neuropathy, which affects the nerves in the hands or feet. Certain medications, such as antibiotics and chemotherapy, can also play a role in causing peripheral neuropathy. In some cases, nerve damage or central nervous system disorders may be the underlying cause of persistent paresthesia.
Other possible underlying health issues that can cause pins and needles include multiple sclerosis, rheumatoid arthritis, and sciatica. If you are experiencing accompanying symptoms such as loss of balance, muscle spasms, or muscle weakness, it is important to consult a healthcare professional.

Temporary nerve damage
Experiencing a pins-and-needles sensation is usually not serious and can be caused by leaning or lying awkwardly on an arm or leg, which either presses against the nerves or reduces blood supply to that area. Changing positions usually quickly restores normal sensation as the nerves start sending messages to the brain and spinal cord again.
However, in some cases, pins and needles can be caused by temporary nerve damage or certain disorders of the central nervous system. Temporary nerve damage, or neuropraxia, is a mild form of peripheral nerve injury where the nerve stays intact but nerve impulses cannot get through. This can be caused by nerves being compressed, crushed, or damaged by inflammation, trauma, or complications from anaesthesia. Symptoms of neuropraxia depend on which nerve is blocked and where, and can include a pins-and-needles sensation, numbness, or a prickling or tingling sensation.
If you are experiencing persistent or frequent episodes of pins and needles, it is recommended to see a doctor for a thorough medical investigation. Treatment for nerve damage depends on the cause and can include rest, splinting, medication, physiotherapy, or surgery.

Frequently asked questions
Pins and needles typically indicate nerve irritation, which can be caused by blocked blood flow or nerve injury. It usually lasts a few minutes and can be resolved by changing your body position. However, if the sensation persists or occurs frequently, it may signal a more serious condition, such as nerve damage or an underlying health issue.
The pins-and-needles sensation, also known as paresthesia, can be caused by various factors, including body positioning, nerve compression, or underlying health conditions. It is often associated with conditions such as carpal tunnel syndrome, sciatica, peripheral neuropathy, or vitamin deficiencies. In some cases, certain medications or supplements can also contribute to paresthesia.
If the pins-and-needles sensation persists or occurs frequently, it is recommended to consult a healthcare professional. It could be a sign of nerve damage or an underlying condition such as diabetes, vitamin deficiency, or multiple sclerosis. Seek medical attention if you experience accompanying symptoms such as muscle weakness, loss of balance, or muscle spasms.
