Raynaud's Disease and Migraine
Raynaud's disease affects 4-15% of the general population. The female to male predominance is 7:1. An association has been found between Raynaud's and migraine. The symptoms are color changes in the fingers and toes in response to cold exposure. The digits sometimes turn first white, then blue, and finally red as a reactive phase. Tingling and numbness can also occur. This happens because of vasospasm, and it is important for your doctor to know about this, because it may affect the choice of medication used to treat your migraines.
Beta-blockers, clonidine, and ergots are contra-indicated as they are vasoconstrictors and can make the condition worse. Smoking also makes it worse. However, calcium channel blockers can be used to treat Raynaud's disease, and this is also a migraine preventative agent. Biofeedback has also been used for Raynaud's, and is also useful in migraine.
