My AVM discovered before it ruptured. I had it surgically removed and I’m totally fine now. No residual issues. I live a normal life. Here’s my post surgery post. I no longer have the symptoms I mention in that post.
You’re lucky to discover it before rupture. And if your doctor is hinting at surgery being an option that is likely also a positive. If the AVM is too big or in a tricky location the decision to excise it can be trickier.
