What Is a Blood Vessel Spasm?
Blood vessel spasms occur when small vessels in the body, usually in the extremities such as toes and fingers, narrow and constrict, preventing blood flow to the affected region of the body. Doctors do not fully understand the cause of blood vessel spasms, but they are usually a result of a disease known as Raynaud’s syndrome. Raynaud’s syndrome typically is diagnosed between the ages of 15 and 40 and affects women nearly five times more often than men. Blood vessel spasms and Raynaud’s syndrome usually are easy to control and treat by preventing situations and elements that cause attacks.
