Raynaud’s disease is a rare disorder that can cause your toes to become abnormally cold in response to emotional stress or low temperatures. When the disease attacks, the skin in your impacted areas may change colors. Initially, your cold toes might turn white, then blue as numbness sets in. Affected areas can later turn red, accompanied by a throbbing or tingling sensation, as circulation improves. If you are experiencing these symptoms, it is likely that you have Raynaud’s syndrome.
The reason this happens is that your body experiences a narrowing of blood vessels, known as vasospasm. This ailment is not particularly disabling in and of itself, but if you suffer from a severe case you could end up developing an infection in the affected toes.
