I am writing this in hopes of helping with my experience
I have had to struggle with my Gp to believe that I was convinced some of my symptoms were due to Low Potassium
It started few months ago with trip to Er with what i thought for sure was a stroke.. turned out Potassium very low.
So I was given a script for a 20 meq supplement and that was 5 days worth and in 5 days many symptoms I had thought might be return of GCA / pmr were gone.
Repeat Bloodwood K showed 3.5 which is the lowest norm,
but GP said no more supplements , didnt make sense to me as it was 3.5 , on supplements , but I went with it.
Over time I have had the tingling in my feet, side of head face , and general weakness in my muscles.
Chugging v8 and taking prevacid for the heart burn that was causing.but that really wasnt helping
Last week , full blown symptoms , same as brought me to ER last time but I refused to wrack up another huge bill, so I called my GP and had to beg for supplements, gave me 5 days worth and within 12 hrs all symptoms gone, this time after 5 days on it my level was 132 , which is still below normal, and they have finally agreed to daily supplement .
Over this time i am also on a non potassium sparing diuretic, urinating constantly, and on pred, triple threat to potassium.
So I would suggest if some symptoms come up like numbness, tingling, sudden fatigue, muscle weakness, difficulty swallowing
explore this. I know it intermingles with all the other pred, pmr gca odditys we all experience but I know first hand it can be from Potassium imbalance as well.
I am now down to 7.5 and i know its when the adrenals need to wake up, I am glad to be in good K range to know whats what
