Numbness of the limbs: "treacherous" reasons – when to see a doctor

Most often, the sensation of “numbness” in the extremities occurs due to pressure on the nerves or blood vessels that supply the nerves.

Numbness often occurs after you have been in an uncomfortable position, such as sitting cross-legged or lying on your arm for a long time. However, sometimes it can also be a sign of a much more serious underlying condition, such as diabetes.

There are several possible reasons for this symptom:

• Standing or sitting in the same position for a long time.
• Nerve injury (such as neck or arm).
• Herpes zoster.
• Poor circulation due to atherosclerosis, frostbite or inflammation of the blood vessels.
• Lack of calcium, or potassium, or sodium, or vitamin B12.
• Radiation therapy.

Numbness can also be caused by other medical conditions, such as:

• Carpal tunnel syndrome.
• Diabetes.
• Migraine.
• Multiple sclerosis.
• Mini-stroke.
• Possible hypothyroidism.

The doctor will determine the cause of the numbness or tingling in the extremities so that the symptoms disappear immediately. For example, if you have carpal tunnel syndrome or low back pain, your doctor may recommend that you do certain exercises every day. If you have diabetes, your doctor will ask you to check your blood sugar levels. The lack of vitamins will be compensated with the necessary vitamin supplements.

However, in any case, consult a doctor IMMEDIATELY if:

• You are weak or unable to move.
• You feel numbness only in the head, neck or lower back.
• You cannot control the movement of your hands.
• You have difficulty speaking, changes in vision, difficulty walking, or weakness.
