Subclavian steal

I'm looking for some true advice.
I went for dopler scan today on my arteries in my neck.
8 months ago all was fine.
But today I have been diagnosed with subclavian steal.
I'm desperate for information as the lady who did scan could not tell me much so I have been googling this and that and it's driving me mad.
Has anyone else been through the same. I am now 12 months post stroke and fear it's going to happen again with this diagnosis.
Thanks sam
