Right arm tingling?

Your tingling in right arm feeling may be short-term if caused by pressure such as leaning on the arm for a long period of time. It can be seen in pregnancy, with migraines, and disorders such as multiple sclerosis, cervical disc disease, and Raynaud’s disease. More serious cases can see a permanent numbness such as with an injury or stroke. Many of these conditions may be the source of your numbness in right arm discomfort; we will examine the related causes and symptoms.

Injury

An injury to the nerves in the arm, neck, shoulder, or even the back can cause a numbness sensation to set in the right arm. Injury can include compression of the blood vessels, an infection, or tissue scarring. Incidents such as frostbite, a herniated disk, or an animal bite may cause damage to the right arm.
2. Carpal Tunnel Syndrome

A common cause of temporary numbness of the right arm is carpal tunnel syndrome. As a specific injury to the median nerve at the wrist region, you may feel tingling and numbness in the lower arm as well as your hand and fingers. You may also experience pain with this disorder. It is associated with pregnancy, rheumatoid arthritis, and common with repetitive motion seen with rotation of wrist.
3. Diabetic Neuropathy

Inflammation of nerves from fluctuating blood sugar levels can present numbness. This is a major symptom of diabetes along with weakness, excessive thirst, and frequent urination.
4. Nutrition Deficiency

We depend on essential nutrients such as vitamins B6, B12, B5, D, and C and pure minerals potassium, calcium, and phosphorous for proper functioning. A shortage of any of these can cause numbness in any part of our body, including the right arm.
5. Toxins

Internal and external exposure to toxins can lead to tingling in right arm discomfort. These toxins range from medications and tobacco to excessive use of alcohol and radiation therapy. Hidden toxins may be found in seafood or may be the result of insect bites.
6. Stroke

Numbness in the right arm caused by a stroke may be linked to the functions of the left side of the brain in most people. This can affect your concentration and speech. Please note that for many left-handed people, the right side of the brain controls the language function. Other symptoms may include paralysis, severe headache, or fainting. A stroke occurs from lack of blood supply due to damaged brain tissue. A precursor to a stroke may be a transient ischemic attack (TIA). This is a partial and temporary blockage of blood supply and numbness is a major symptom.
