Suffering From Itchiness In Hands And Feet

hi, two weeks ago I started with a very intense pain in my left hand side (back) around the kidney area. I then had bleeding when I went to the toilet for a pee. I went to the doctors had my pee tested. my result came back with I have ecoli, she thinks in my kidney, my white cell reading was 4240 if this makes sense to you. she put me on antibiotics for two weeks, last one day today, but since last Wednesday I have been suffering really bad with itchy hands and feet. I still have the pain in my back, I am extremely tired all day long even if I rest and do nothing. it hurts also after sex, like my ovaries are on fire. any clues what is going on with me please?
