Hi all, I understand that low blood Potassium can cause RLS or make it worse. There's also a tie up with Magnesium I believe. Just wanted to say that I'm on various tabs for high blood pressure, can't do without, been on for years. I have yearly blood checks. Though usually normal this time have low potassium, most likely due to diuretic Bendroflumethazide. RLS awful just now. Am hopeful getting potassium up again will help. So just reminding to keep checking everything relevant. Because normal once doesn't mean always will be. We all need every tiny bit of the jigsaw to be as perfect as possible. And due to my own fault was way behind when I should have had this recent test!
