What would cause blacking out and numbness in your leg?

There are many possible causes of blacking out and numbness in your leg. Some of the most common causes include:

* Blood clot: A blood clot in the leg can block blood flow to the leg, causing pain, swelling, and numbness. If the blood clot is large enough, it can also cause blackouts.

* Nerve damage: Nerve damage can occur as a result of a variety of conditions, such as diabetes, trauma, or infection. Nerve damage can cause numbness, tingling, and pain in the leg.

* Artery disease: Artery disease is a condition that affects the arteries, which are the blood vessels that carry oxygen-rich blood from the heart to the rest of the body. Artery disease can cause pain, numbness, and blackouts in the leg.

* Spinal cord injury: A spinal cord injury can damage the nerves that carry signals between the brain and the leg. This can cause numbness, tingling, and pain in the leg.

* Certain medications: Some medications, such as chemotherapy drugs and antidepressants, can cause blackouts and numbness as side effects.

If you are experiencing blackouts and numbness in your leg, it is important to see a doctor to determine the cause and get appropriate treatment.
