i think i have a kidney infection, i have had kidney stones for ten years. i have lost alot of weight, dehydrated, and havent gotten much sleep. i noticed my skin was very pale and turned yellow, as did my eyes. i thought it was from not getting sleep, i have taken antibiotics i had from a different uti. should i be worried about organ failure? my heart has been beating faster than normal and having very bad anxiety an paranoia. i got a fever but hands and feet were ice cold. is this signs of kidney, heart, or liver failure?
