Right Arm Numbness

Right arm numbness isn’t generally associated with one specific medical condition, so it can be a confusing symptom. It may be brought on by injury, or as part of a disease impacting your circulatory system. Tingling and numbness in the arm, hand, leg or foot can be brought on by various conditions. Pay close attention to any other symptoms you may be experiencing at the same time.

Right Arm Numbness – Possible Causes

If you’re experiencing numbness in your right arm, it’s helpful to know what health issues may bring it on.

  • Stroke

This is the most serious medical condition that can bring on numbness. We’re bringing it up first, because if you also have other stroke symptoms, you need to seek immediate medical attention. Right arm numbness is certainly not always indicative of a stroke.

If a stroke affects the parts of your brain that control upper limb movements, then you may experience numbness or weakness. It is caused by neurological damage to your brain tissue, because of a loss of blood supply.

If you are having a stroke, your numbness will likely be accompanied by a severe headache and even loss of consciousness. Paralysis associated with stroke is usually only on one side of your body.

A quick way to determine if someone is having a stroke uses the word FAST.

F – Face will droop on one side.

A – Arms – if you hold both arms up, the one on the affected side will not lift as high.

S – Speech may be slurred/

T – Time is of the essence. Get medical help immediately.

As seen in this FAST clue, most stroke cases require urgent care in a timely manner. Depending on the reason for a stroke, you may be treated with anti-coagulation therapy. If you have a hemorrhagic stroke, on the other hand, the treatment plan is different.

Most stroke cases do respond gradually and slowly to holistic treatment and rehabilitation. This may include strength exercises, physical therapy and speech therapy.

  • Lacking in Nutrition

If you don’t have enough calcium, sodium, potassium or vitamin B12 in your system, this may lead to right arm numbness. Some medications may cause arm numbness, if they affect circulation. Excessive tobacco or alcohol use may cause nerve damage in the arm, which may lead to tingling or numbness.

  • Lack of Proper Circulation

Some minor circulation issues may cause right arm numbness. Sitting or standing in one position for a long time may cause a drop in circulation, which may lead to numbness in the arms. You may also feel tired, dizzy or faint.

  • Shingles Virus (Herpes zoster)

This virus can cause numbness in your limbs. The disease usually brings sores on your body, as well.

  • Injuries

Injuries may lead to numbness or tingling in the arm. Injuries that lower your circulation may cause numbness. This would include medical issues like atherosclerosis or frostbite. Pinched nerves in the neck or back may also cause right arm numbness.

Herniated discs can place excess pressure on the nerves that lead to your arm, which causes you to feel fewer sensations. Animal bites striking nerves can also lead to numbness. Infections in the arm itself may cause the blood vessels to become compressed, leading to numbness.

  • Toxins

Exposure to certain toxins can cause numbness in your arm. Radiation therapy for cancer may cause tingling or numbness. Seafood toxins can cause numbness, too. Some bites from insects like ticks, mites or spiders may cause your right arm to feel numb. This type of bite leaves a swollen, red mark when the insect actually bit you.

  • Long-term medical issues

These may cause your right arm, or other areas of the body, to become numb.

  1. Carpal tunnel syndrome in your right wrist may cause numbness in your hand or arm.
  2. Multiple sclerosis may lead to lack of sensation, numbness or tingling.
  3. If you suffer from seizures or migraines, you may feel some right arm numbness or other localized tingling before an attack starts.
  4. Diabetes and underactive thyroid symptoms can include limb numbness, because of circulation changes caused by those conditions.

Treating Right Arm Numbness

You can treat numbness through medical treatments or home remedies. Read on for some information about both methods.

Medical Treatments

Numbness that begins suddenly or along with loss of bladder control, slurred speech, weakness, difficulty in moving or vision changes should be seen as the medical emergencies they are. These are symptoms of stroke, and you need help immediately.

If you don’t have any other symptoms, but your right arm numbness could have been caused by an injury to your neck, head or back, seek out medical attention immediately, as well. Don’t move your back, neck or head until a medical professional arrives. This is to avoid further injury.

If the numbness in the arm lasts for several days or without obvious cause, contact your physician for an exam.

If your numbness appears along with symptoms like spasms, dizziness, rash, pain in fingers, neck or arm or frequent urination, or if your numbness worsens when you try to move the arm, this may be a serious medical condition. Consult your physician or have someone take you to an urgent care facility.

Home Remedies

If your numbness was caused by injury, you can use home care to relieve your symptoms.

If you suffer from a vitamin deficiency or low blood sugar, you can simply adjust your diet to include more of those nutrients. B12 or calcium supplements can be helpful. If you have only recently started taking a new medication that causes numbness, speak to your physician to see if you need to have that prescription changed.

Take any precautions necessary including wrapping your limb, so that you don’t cause any further injury. Don’t overwork your arm. Rest quietly to promote proper healing.

If a portion of your back or neck is swollen, and this is causing your right arm numbness, take anti-inflammatory OTC medications and apply warm compresses to your arm.

Stretch your arm gently or move it around a bit to relieve tingling or numbness, if you have no other symptoms. If your arm gets numb frequently, speak with your physician about setting up an exercise regimen that will elevate your heart rate for 15-20 minutes per day.
