Doctors will treat any health problems causing your Raynaud syndrome.

If you get symptoms when excited, do biofeedback therapy or take sedatives
Take medicines to widen your blood vessels, such as calcium channel blockers
As a last resort, doctors may do a procedure to cut certain nerves that control the size of your blood vessels. Even when this procedure helps, symptoms often come back in a year or two.
