What would cause both legs to go completely numb when sitting?

Sitting in a position that puts pressure on the nerves in your legs can cause your legs to go numb. Here are a few things that could be causing this:

- Crossing your legs: Crossing your legs can put pressure on the sciatic nerve, which is the largest nerve in the human body. This can lead to numbness and tingling in both legs.

- Sitting on your wallet or purse: Sitting on a hard object like a wallet or purse can also put pressure on the sciatic nerve. This can cause similar symptoms to crossing your legs.

- Tight clothing: Wearing tight clothing, such as jeans, can also restrict blood flow to your legs and cause them to go numb.

- Peripheral neuropathy: This is a condition that damages the nerves in your body, which can lead to numbness and tingling in your legs. Peripheral neuropathy can be caused by various conditions, such as diabetes, alcoholism, and chemotherapy.

- Lumbar spinal stenosis: This is a condition that causes the narrowing of the spinal canal in the lower back. This can put pressure on the nerves in the legs and cause them to go numb.

- Multiple sclerosis: This is a chronic autoimmune disease that affects the central nervous system. MS can cause a wide range of symptoms, including numbness and tingling in the legs.

If you're experiencing numbness in your legs, it's important to see a doctor to rule out any underlying medical conditions.
