Symptoms of a ruptured brain aneurysm come on suddenly and include a severe, sudden headache that is different from other headaches an individual has experienced. Other symptoms of rupture are neck pain, sensitivity to light, nausea, vomiting, seizures, fainting, and loss of consciousness.
Most people with a thoracic aortic aneurysm do not have any symptoms. Often, the aneurysms grow slowly and go unnoticed. Many never reach the point of bursting; others enlarge quickly. When the aneurysm expands, you may notice chest pain, lower back pain, coughing, hoarseness, or difficulty breathing.
