What causes Raynaud's phenomenon?
In many cases, there is no underlying cause for Raynaud's phenomenon; rather, it is thought to be caused by an exaggerated response of the blood vessels to cold temperatures or stress. In some cases, it can occur due to underlying medical conditions, exposure to certain medications and chemicals, or injury.
