How do I know if I have CVS?
A doctor can diagnose CVS based on a thorough history, physical exam, and the symptoms. There is no test for CVS. Tests may be done to rule out other conditions. A viral infection may at first be suspected. Repeated trips to emergency rooms are not uncommon, especially until a diagnosis is made. Many people with CVS also report migraine headaches or a family history of migraines.
What causes CVS?
The cause of CVS is not yet known. Scientists are looking at genetic, hormonal, and other factors that may contribute to the symptoms.
