about a week ago I got really sick i thought it was food posioning due to the symptoms {high fever between 103-105, my sides around my kidneys hurt, bad headache, confusion,and my bones and muscles were siezing up, blood in urine} realize probably should have called a doctor but after a couple days as food posioning does it started to subside. But now it keeps coming back but not all together sometimes kidneys hurt, sometimes a fever, etc.. now there is little to no blood in the urine but ther is like chunks i am currently taking d-mannose figuring this is some sort of UTI but would like to hear another opinion {i am aware i could take antibiotics but i have severe allergy to penicilin and not sure of alternatives that are safe for me}
