... potassium is my GP is a caring and understanding person. I have been to several nephrologists and they act like this is all in my head. My GP would rather not give me the prescription, and believe me it isn't enough to sustain me, I have to supplement with OTC potassium too to keep my levels in the normal range. I just do not know what to do. I can tell when I am low, my muscles hurt and I am extremely fatigued. This has hurt all aspects of my life and frankly it is a struggle everyday. My question is I go through some times where I sweat continuously even though I am sitting in air conditioning. I find when this happens I need even more potassium, does anyone know why all of a sudden sweating occurs? Also is there doctors other than a nephrologist or endocrinologist that can help me with this?
