Why do fingers and toes turn red throb at night?

There are a number of reasons why fingers and toes may turn red and throb at night. Some of the most common causes include:

* Raynaud's disease: This is a condition in which the blood vessels in the fingers and toes narrow, restricting blood flow. This can cause the fingers and toes to turn white, blue, or red, and they may also feel cold, numb, or painful. Raynaud's disease is often triggered by cold weather or stress.

* Peripheral neuropathy: This is a condition that damages the nerves in the fingers and toes. This can cause a number of symptoms, including numbness, tingling, pain, and weakness. Peripheral neuropathy can be caused by a variety of factors, including diabetes, chemotherapy, and certain medications.

* Arthritis: This is a condition that causes inflammation of the joints. This can cause pain, swelling, and stiffness in the joints, and it can also affect the blood flow to the fingers and toes.

* Heart disease: Some types of heart disease can cause the blood vessels in the fingers and toes to narrow, restricting blood flow. This can cause the fingers and toes to turn red, blue, or white, and they may also feel cold, numb, or painful.

* Blood clots: Blood clots in the arteries or veins in the fingers and toes can also cause them to turn red, blue, or white, and they may also feel cold, numb, or painful.

If you are experiencing any of these symptoms, it is important to see a doctor to determine the cause and get appropriate treatment.
