I went to one ER they told me I had a staghorn stone 1.2 cm in my left kidney and to take keflex for uti infection. They said stone had to be removed it was odd shaped and to big. A few days later I am very sick and out of town and go to another ER I am on way to get another CT and the first ER calls me tells me to stop taking keflex take bactrim cause culture came back and I need stonger one. I tell the ER doc this anyway this ER doc tells me I don t have staghorn stone just regular stone and didn t perscribe antibiotics I told him they called in bactrim. So here it is two or three days later I am sic as a dog I am at home and in bed all day thinking should I go to ER. I am thinking I feel poison iny body and I am hurting all over. I am lying here and get a call from last ER I was seen in and the nurse tells me if I am taking any antibiotics to stop and he has to call me in one called macrobid. I then go on line and check my lab results and noticed my creatine level was 1.18 . I feel like by now I probably need iv antibiotics I don t know. Is this creatine level ok and do you think the antibiotic I am on now will do the trick? Do I have a staghorn stone or not? How will I know for sure cause this can t be good being in my kidney right?
