Hi CH fam - Last week I convinced my neurologist to prescribe oxygen for me. I've never tried oxygen for my CHs before, and I'm praying that it works so that I can ease off the Relax, which I'm taking every day. My neurologist told me was going to prescribe an oxygen concentrator. I just googled this, and it's different from getting an O2 tank, which is what I was expecting. Does anyone have any experience using an oxygen concentrator? Tips? Advice? Thanks!
