Hi all, had some issues recently very sore back, frequent urination, tired, irritable, headaches, high BP etc. am only 31, doc rang today and said blood test showed quite high kidney levels and that would only occur as an error if I was severely dehydrated when blood was taken. Got to have repeat bloods in two weeks and an a ultrasound of kidneys and bladder. Anyone know what else could cause this?. I do take talents for epilepsy that can cause kidney stones but never had issues with these. Am bit worried now :( I've been waking with awful backache which I never ever get either
