I suffer from chronic migraines the pain so location where the AVM was the question is, if the AVM is gone then why am I still have been headaches? The reason why I ask is because the signs and symptoms mention "migraine-like," and background:

A cerebral arteriovenous malformation is an abnormal connection between the arteries and veins in the brain that usually forms before birth.
In about half of patiens with AVMs, the first symptoms are those of a stroke caused by bleeding into the brain.

Symptoms of an AVM that has not bled include:
•Confusion
•Ear noise/buzzing (also called pulsatile tinnitus)
•Headache •May be in one area (localized) or the entire head
•May resemble a migraine headache in some cases

•Problems walking
•Seizures of all types and severity
•Symptoms caused by pressure on one area of the brain •Blurred, decreased, or double vision
•Dizziness
•Muscle weakness in any part of the body or face
•Numbness in any part of the body

Can someone explain this to me?
