Many people who have fibromuscular dysplasia don't have any symptoms. For those who do, signs or symptoms of the disease depend on which artery or arteries are affected. If the arteries to the kidneys are affected, common signs and symptoms include: 
High blood pressure
Poor kidney function
 If the arteries affected supply blood to the brain, signs and symptoms might include: 
Headache
Pulsating ringing in your ears (tinnitus)
Dizziness
Sudden neck pain
Stroke or transient ischemic attack (TIA)
