Arm tingling, also known as paresthesia, results from dysfunctional operation of nerves in the left arm. Often, people misdiagnose this symptom as something to be ignored.
What Are Causes of Tingling in the Left Arm
When experiencing tingling in your arm, whether it is your left or right arm, it could be due to paresthesia, which means that you are experiencing abnormal skin sensations, such as tingling or burning and itching. Paresthesia is generally the outcome of peripheral nerve damage.
- The Mayo Clinic explains that nerve damage can cause peripheral neuropathy, signaled by tingling and numbness. Nerve damage can be the result of infection, injury, exposure to toxins and metabolic problems. Diabetics often suffer from nerve damage.
- Tingling in the arm can be caused by a subluxated first rib, which is referred to as a thoracic outlet syndrome. When this occurs, the nerve and artery in your neck may be pinched, causing diffuse tingling rather than tingling in one particular part of the arm, according to Chriopractic-help.com. This is described as a dermatomal pattern.
- An example of dermatomal pattern is when you feel tingling in the upper arm on the side and perhaps also in the lower arm. This is called C5 dermatome and can lead to weak biceps and deltoid muscles as well as tennis elbow if not treated.
- An irritated neck nerve causes your skin to become very sensitive. Eventually your arm could become numb.
- The joints in your neck must move in order to remain healthy. If something happens that fixes these joints and they are no longer movable, this starves the cartilage of nutrients and oxygen and noxious waste products build up. The waste products irritate the nerve in your neck, which causes arm tingling.
Arthritis or Slipped Disk
- If you have arthritis and changes occur within the forearm as a result of this condition, this can result in pain in your arm as well as tingling. Tingling in the left or right arm can also be the result of a slipped disk in your back.
What Does it Mean Tingling in the Left Arm?
- The tingling in the left arm could indicate a stroke symptom. Look for signs of severe headaches, difficulties in speech, visual distortion and poor coordination.
- If you experience tingling in the left arm accompanied by tightness in the chest and stiff jaw pain, call 9-1-1. These are heart attack symptoms.
Carpal Tunnel Syndrome
- If your occupation includes extensive use of your fingers and hands, the tingling sensation in your arm could be caused by blocked circulation due to a pinched nerve in the wrist, a condition called Carpal Tunnel Syndrome. Office workers, mechanics or musicians who grip objects constantly usually experience Carpal Tunnel Syndrome.
- Tight clothing, jewelry and improper sleeping position can constrict blood flow. People also describe such symptoms in euphemisms such as “my arm is asleep.” Uncomfortable sleeping or awkward reclining positions cause this arm tingling sensation.
- Tingling sensations in the left arm occur if you suffer from and kind of vascular problem, which constricts blood circulation. People who suffer from diabetes, muscular sclerosis and migraines also experience tingling sensations.
- Do not ignore the tingling sensations in your left arm, and make sure to contact 9-1-1 for stroke and heart attack symptoms.
