I thought I had a kidney stone, now after a month of feeling very sick I finally went to the ER. I was told I was dehydrated and had a temperature of 103. After a CAT Scan I found that I had a kindey stone and a kidney infection. I was prescribed Vicodin for pain and Levaquin 500MG for the infection. I have taken one a day for seven days and have 4 left. I stopped taking the Vicodin because I didn't like the way I was feeling. That has helped but now I am feeling bad in different ways. I sometimes have a steady pain in my heart which seems to extend down into my stomache. Which seems odd to me and my neck is killing me. It is like I slept on it wrong but rather than at one angle or in spot it is my entire neck, right up into the base of my skull. About 4:30 a.m. this morning I woke up feeling very sick to my stomache and hot. I woke up several times last night hot, sweating hot, which was very uncomfortable. I am not even sure any of this is from the Levaquin but it's very uncomfortable and a kind of scary. My heart rate also seems high and I just don't feel right.
