Anyone ever had potassium deficiency?

Well I'd been having symptoms for weeks as it was dropping lower and lower. I got all my bloods back from hospital n could see it dropping each time. At a level of 3.4 I nearly had a heart attack, even though this is only one point below the 'normal' range which is 3.5-5.0. Most people need to be at least 4. I was 4.5 before I got sick. They gave me 5 potassium pills in emergency department n the levels went up to 4.2/4.4 which is impossible after only 5 pills you'd need months of supplementation to bring it back up to that. It's very hard to build back up well it's like any deficiency it takes time to build back up. I was having severe symptoms like lbp heart palps excessive thirst weakness n bloods were showing high levels of k which is simply impossible after no supplementation. I'd all symptoms just bloods didnt match. Eventually after one month of severe suffering my bloods came back down to 3.4 in which no one even bothered to take note of it was then I knew it's k n started drinking lots of coco water n symptoms resolved but it was very hard to do with diet alone. My body was starved of potassium n no1 even believed me as the bloods were wrong but I'd every single symptom you could even see me dehydrating n thirsty lbp etc..it was awful. So they had to be falsely elevated. Also 2days after this 3.4 reading (which I got later when I rang) I was fainting with lbp n had no choice but to go bk to hospital n the reading that day was hemotosed meaning inaccurate due to shaking n read 4.2 that's impossible to be 3.4 one day n 4.2 the next. I kept asking doctor is something wrong with electytes she kept saying no n never even bothered to repeat the test even though it was hemp stupid or what like that's why lab puts it on there as it's incorrect. Potassium is particularly susceptible to this n despite the fact I was drinking 4 litre of water per day which is obviously abnormal. Had they have retested they would have seen it or matched my symptoms...they treated me like I was mad!!

It was awful. Iv to go back to doctor this week 4 more supplements n I'm having awful tummy probs so couldn't even take supplement s 4 ages as they hard on stomach. It's all so tough if I ever get better n over it I'll be writing in a big complaint to hospital n doing blog on it.

Also things like acidosis can falsely elevated potassium levels when in fact there is none in overall storage. Only 2% of k is in blood the other 98% is in the cells so bloods can be inaccurate. There is an intracellular blood test or rbc whole blood which checks overall stores.

They sure are and tests can be wrong they are only tests not God the body is complex n things can put out balance n interfere with accuracy of results. It's sad they believe this over a person.
