Hi Reni, I too have not had this experience, but my daughter has and is now watching another. Hers are now found toe related to FMD Fibromuscular Dysplasia. She had a great surgeon at the Mayo clinic in Portland area but is now seeing a new neurosurgeon here in Boise area. This new one will be watched and hoping to fix within the next 6 months with a coil procedure. Not sure yours can be treated this way. I have MA and have had shots in my eye for more than 10 years to keep my vision, so I totally feel your fear of loosing your vision. As stated above, look to your surgeons, find the best, someone who has performed many, many successful ones, and pray !
God Bless, Cheri
