Thank goodness for this thread. i have been complaining about muscle weakness for a long time. The last 3 weeks in Toronto I have fallen three times in stores. One day i was in the grocery store and my legs gave out on me and I just crumpled. i didn't have the strength to get myself up so they had to call two guys to the front of the store to lift me up. It caused quite a scene and would you know it...5 minutes more i went down again. They were asking me if I was on drugs and all sorts of embarrassing questions. They went to the parking lot and got my fiance and he picked me up. I was in tears mostly due to embarrassment. I finally went and bought a cane that day. Around the same time i was told my potassium was high at 6.2. I have never had a high potassium level before. I haven't changed my diet so I couldn't figure it out. I never connected the potassium and muscle weakness until i read this thread. How long does it take before the muscle weakness goes away?
