<s>[INST] Hi. I have been having a pain in my left kidney area for a about 5 days now. (I have been having issues off and on with kidney stones since November, so the pain is familiar) The pain has been a steady 4-5 with sharp pains at about a 7. I have also had a low grade fever off and on this whole time. I have very low energy and have been sleeping alot. Is this something I should go seek medical attention on or is it just another kidney stone? What are the signs of an infection versus a stone? [/INST] Hello and welcome to Chat Doctor.
