Steps to follow:


One of the most common causes of numbness in the legs is staying too long in one position. This occurs because of inadequate blood circulation i.e., if the blood does not circulate properly to that body part, you will feel a tingling sensation. Colloquially we say "my leg fell asleep".

Furthermore, nerve damage can also lead to numbness of limbs. For example, disorders related to the spine: herniated disc, dislocation or fracture of vertebrae, nerve entrapment... may cause you to feel constant tingling in one or both legs.


Peripheral arterial disease (PAD), also known as peripheral vascular disease, is another cause of numbness in the legs. This is a narrowing of the arteries by the build-up of fat and cholesterol on artery walls. Thus, blood doesn't flow properly to the limbs and tingling occurs.


Blood clots in the leg may cause numb limbs and, in turn, may result in venous thrombosis and pulmonary embolism and cause a heart attack, a stroke...


Note that there are many diseases that can cause numbness in the legs, Including:

  • Fibromyalgia
  • Diabetes
  • Hypothyroidism
  • MS
  • Amyotrophic lateral sclerosis
  • Seizures

Thus, we can see there are many factors that cause numbness in the legs, so a medical specialist should examine the problem and determine the correct diagnosis.
