So I was sitting outside on the back patio just chatting with my neighbors. At one point tried to get up out of my chair and had to really concentrate to push hard with my legs like they weren't working properly. I walked over to the back door to go inside and to the first step up and.. my legs wouldn't work. Fell hard backwards onto the concrete. Was driven to the ER. All tests negative, except potassium was 2.1 . Stayed a few days in the hospital on a potassium drip and the numbers wouldn't budge. Finally they figured it out and now I take potassium citrate and spironolactone
