Fibromuscular dysplasia
Fibromuscular dysplasia (FMD) is a disease that causes narrowing, beading, bulging (aneurysm) and dissections in the medium to large arteries in the body. Headaches and ringing in the ears are two of the most common symptoms reported in FMD patients.
“Headaches, mainly of the migraine type, are observed in up to 70% of patients with FMD.”1
Genes such as PHACTR1 have also been associated between FMD and migraine.
