@Baby Moth, as evidenced by @BoscoPiko's reply, you sure came to the right place!
Since Bosco covered the big stuff very nicely, I'll just follow with a bit of additional color:
If left alone, or treated with certain pharmaceuticals it could, yes, but IT'S NOT GOING TO because you've happened upon the Blue Banner, D3 regimen, etc., that often enable us to prevent entire cycles - a big and most welcome deal.
Great that you've had the O2 prescribed. It can be essential to know that high flow/non rebreather mask O2 can really make it work great if it isn't 100% working to abort attacks when following a typical low flow etc. prescription.
