did your doctor check you for raynaud's? see below and discuss it.
Signs and symptoms
Raynaud's disease is more than simply having cold hands and cold feet, and it's not the same as frostbite. Signs and symptoms of Raynaud's depend on the frequency, duration and severity of the blood vessel spasms that underlie the disorder. Signs and symptoms include:
Sequence of color changes in your skin in response to cold or stress
Numb, prickly feeling or stinging pain upon warming or relief of stress
At first during an attack of Raynaud's, affected areas of your skin usually turn white. Then, the areas often turn blue and feel cold and numb, and your sensory perception is dull. The affected skin may look slightly swollen. As circulation improves, the affected areas may turn red, throb, tingle or swell. The order of the changes of color isn't the same for all people, and not everyone experiences all three colors.
Occasionally, an attack affects just one or two fingers or toes. Attacks don't necessarily always affect the same digits. Although Raynaud's most commonly affects your fingers and toes, the condition can also affect other areas of your body such as your nose, cheeks, ears and even tongue. An attack may last less than a minute to several hours. Over time, attacks may grow more severe.
People who have Raynaud's accompanied by another disease may also have symptoms related to their underlying condition.
