Common Reasons You’re Experiencing Arm Tingling

Must read

In this informative text, I am going to talk about a feeling that might have called your attention: the feeling of a tingling arm. Although this symptom might not be painful, it can be worrying in certain cases. Numbness in the arm has many possible causes that range from mild to severe.

Simply sitting or sleeping in the wrong position can restrict the blood flow or put excess pressure on a nerve, making the arm go numb. However, it is important to pay attention when arm numbness is unexplained since it may indicate an underlying health condition.

Here you’ll find a guide to some questions you might have asked yourself before. Let’s check out some of the most common reasons for feeling tingling in the left arm:

Why is my arm numb?

Have you ever experienced numbness in one or both of your arms? There are many reasons that can cause arm numbness and they range from mild to serious. In this article, we are going to briefly explain some of the possible reasons you might be experiencing arm numbness. 

You should take into account that if this feeling is recurring, you should definitely visit your doctor.

Here is the Common Reasons List:

Rheumatoid Arthritis

Rheumatoid Arthritis (RA) is an autoimmune disease and it may cause inflammation in joints, hands, and feet. The primary treatment for this condition is medication, and getting early treatment can help relieve symptoms and slow the disease’s damage to the body.

Staying as active as you can help you feel better. It is also important to keep in touch with a physical therapist to assist you in developing a fitness routine to keep you strong and flexible.

Carpal Tunnel Syndrome

People with CTS suffer from pinched nerves in their wrists. This occurs when a nerve in your wrist, called the median nerve, becomes compressed. The pinched nerve causes numbness, pain, and tingling. The pain can reach all the way to the shoulder.

Warning: CTS is often caused by repetitive motions over time (typing on a keyboard for work can be a good example)

This is the reason why taking breaks to let your wrists and arms rest is a good first step to keep the symptoms at bay. Some of the treatments include ice, cortisone shots, physical therapy, and surgery. People suffering from CTS  are often given wrist splints to wear to hold their wrists in place.

Cubital Tunnel Syndrome

This occurs when there are problems with the ulnar nerve, also known as the “funny bone.”  The usual causes of this are due to holding the elbow in a flexed position for too long, which stretches the nerve, or directly putting pressure on the funny bone.  

Patients usually experience numbness and tingling that starts at the elbow and shoots down into the pinky and ring finger. Research has shown that most of the time, tingling in the hands isn’t a worrying thing.

It can be temporary, due to stress, or from trauma. Remember we are so used to using the keyboard on the computer that we don’t realize that it is a new tool and a new position for our bodies.

For you to worry or not about these symptoms it is important that you can differentiate if the symptoms are episodic or chronic. If you realize the tingling is temporary, it is probably caused by trauma. However, there are some cases when the tingling in the hands is chronic and constant in time.

Be careful when playing on your cell phone for too long and with bad sleeping positions since these put your elbow in extreme flexion!

Tennis Elbow

It is a term used to describe swollen tendons in the elbow that may cause pain, weakness, numbness, and tingling in the outer elbow. Its name comes from the fact that it is a common injury for people who play tennis.

Some home remedies for tennis elbow are: resting your arm, ice, and taking a nonsteroidal anti-inflammatory. If home remedies don’t reduce the symptoms, you should try using an elbow strap or getting physical therapy.

Pinched Nerve

It is said that a nerve is “pinched“ when it is compressed due to pressure from nearby tissues or bones. All of the nerves that supply the muscles and sensation to the arm originate in the neck.

So, if there is compression of the nerves in the neck, the entire arm can be affected. Depending on the nerve that is involved, these symptoms usually start in the neck and can involve the shoulder, upper arm, forearm, hand, or even all of them.

A pinched nerve in the neck can cause: numbness in the arm and hand and it can also cause pain and weakness. 

Some suggested home remedies for a pinched nerve are rest, heat, ice, and taking a nonsteroidal anti-inflammatory. If you see that these treatments do not relieve your symptoms or if your pain is severe or recurring, please go see your doctor.

Thoracic Outlet Syndrome

This syndrome refers to three types of disorders that involve nerves or blood vessels that are being compressed in the upper torso and throat. The symptoms can include pain, numbness, and tingling in the neck or arms. 

The treatment for thoracic outlet syndrome generally depends on which of the three disorders is causing the symptoms.

However, physical therapy and a structured exercise routine are employed along with nonsteroidal anti-inflammatory medication. It may also require surgery or other medications.

Cervical Stenosis

It is primarily a degenerative disease that affects people over 50 years of age. Also, a small percentage of them are just born with it. The symptoms can range from mild to severe. Mild symptoms can include pain in the neck and arms.

It is also possible to feel numbness and tingling in the arms and hands can also occur. More serious symptoms include weakness in the arms or legs, instability when holding objects or walking, or loss of bladder or bowel control. 

Treatment for cervical stenosis depends upon the severity of pain the person is suffering. If it is diagnosed at an early stage of it, it is possible to find  relief after making changes to take the pressure off the neck:

  •  Applying ice and heat can also be beneficial
  •  Physical therapy sessions:
  • Standing or sitting with good posture and using ergonomic measures regarding computer use may help most.

Poor Circulation

There are a variety of underlying medical issues including diabetes, obesity, peripheral artery disease, and blood clots that can cause poor circulation. Some of the signs that can appear when someone has poor circulation are numbness and tingling in the hands, legs, and feet.

Depending on what is causing the poor circulation, the treatment will vary: Walking and other exercises are a good way to improve your circulation

Reduced blood flow can cause other symptoms, such as:

  • – Cold hands and feet
  • – Extremely pale or blue-tinted skin
  • – Swelling in the legs, ankles, and feet
  • – Fatigue
  • – Joint or muscle pain

Rotator Cuff Injury

The group of shoulder muscles that help support the shoulder and assist with arm rotation is known as the rotator cuff. 

When these muscles are injured, pain can occur with shoulder movement.  This pain can radiate down the arm, sometimes with overhead activity, but usually all the way into the forearm. 

  • Possible serious causes associated with it:

Heart Attack

A heart attack occurs when the heart does not receive the oxygen-rich blood needed. A blood clot or plaque buildup can create a partial or complete blockage in one or more of the blood vessels that supply the heart and cause a heart attack. Doctors will attempt to open the blocked artery and restore blood flow to the heart. The treatment will depend on:

  1.  the location of the blockage,
  2.  the person’s overall health status, 
  3. and the amount of time that has elapsed since the heart attack began.

The regular symptoms indicating a heart attack, include:

  • pain or discomfort in one or both arms
  • intense pressure in the chest
  • pain in the upper stomach, which may feel like indigestion or heartburn
  • shortness of breath

Other symptoms include:

  • pain or numbness in the back, shoulders, neck, or jaw
  • feeling lightheaded or faint
  • nausea and vomiting
  • sweating

Warning: A heart attack is a serious medical emergency. People should call 911 immediately if they think that they or someone else is facing a heart attack.

A stroke takes place when something restricts or completely blocks blood flow to part of the brain. Strokes often cause numbness in one arm, leg, or side of the face. 

Other symptoms include:

  • a sudden, severe headache
  • vision changes
  • confusion
  • difficulty speaking
  • dizziness
  • loss of coordination

Warning: A stroke is a serious condition that requires emergency medical treatment.

  • When to see a doctor

Although arm numbness is a common symptom of many minor issues such as temporarily cutting off the circulation, it can also be a sign of a heart attack or stroke.

It is important to bear in mind that if you have a high risk or history of cardiovascular disease, you should seek immediate medical attention in case you experience unexplained numbness or tingling in your arm since it may suggest an underlying medical problem that requires physical therapy or surgery.


Occasional numbness in one arm is generally experienced by many people. It can occur due to many reasons: (mild) sleeping in the wrong position, to (a severe medical condition) such as a heart attack. Anyone who has arm numbness without an obvious cause should contact their doctor, especially if they have a history or increased risk of cardiovascular disease or diabetes…
