Kidney disease?

[jambo53]

Hi there, about a month and a half ago I started feeling like something was always under both my ribs and it has been persistently like this and it's really uncomfortable, I'm also always itchy at night and have been feeling really dizzy and lightheaded constantly. I've went to my doctors and they took my bloods and all that came up was that my potassium levels were slightly high. I've searched this up and it's related to your kidneys and I've also read about night time itching and other symptoms I've been feeling make me worried I have kidney disease. I'm to go back in to get my bloods retaken to make sure my potassium levels being elevated were just a one off. Do people think I could have kidney disease?
