thank you for query
There are many possible causes of numbness and tingling:
• Sitting or standing in the same position for a long time
• Injuring a nerve (a neck injury may cause you to feel numbness anywhere along your arm or hand, while a low back injury
can cause numbness or tingling down the back of your leg)
• Pressure on the nerves of the spine, such as from a herniated disk
• Pressure on peripheral nerves from enlarged blood vessels, tumors, scar tissue, or infection
• Shingles or herpes zoster
• Lack of blood supply to an area (for example, from atherosclerosis
• Other medical conditions, including:
o Carpal tunnel syndrome
(pressure on a nerve at the wrist)
o Multiple sclerosis
o Transient ischemic attack
(TIA), sometimes called a "mini-stroke"
o Underactive thyroid
o Raynaud's phenomenon
• Abnormal levels of calcium, potassium, or sodium in your body
• A lack of vitamin B12 or other vitamin
• Use of certain medications
• Nerve damage
due to lead, alcohol, or tobacco
• Radiation therapy
• Animal bites
• Insect, tick, mite, and spider bites
• Seafood toxins
Your doctor should find and treat the cause of your numbness or tingling. Treating the condition may make the symptoms go away or stop them from getting worse. For example, if you have carpal tunnel syndrome or low back pain
, your doctor may recommend certain exercises.
If you have diabetes, your doctor will discuss ways to control your blood sugar levels.
Low levels of vitamins will be treated with vitamin supplements.
Medications that cause numbness or tingling may need to be switched or changed. Do not change or stop taking any of your medicines or take large doses of any vitamins or supplements until you have talked with your doctor.
Because numbness can cause a decrease in feeling, you may be more likely to accidentally injure a numb hand or foot. Take care to protect the area from cuts, bumps, bruises, burns, or other injuries.
