hi i have been sick for almost 2 months. I missed my period in march and thought i was pregnant, tests came back negative but i had really bad pressure like pain in my bladder area, as well as frequent need to urinate with not very much coming out and cloudy smelly urine. By the time i thought of a bladder infection my back started hurting all of a sudden and i got a fever and began vomiting. I went to the ER where they said it seemed like a bladder kidney infection and put an IV with liquids and antibiotics. All my tests came out normal though, even the renal ultrasound came back normal. They sent me home with a 7 days course of Suprax. It didn't start helping till the second to last day. and now its been almost two weeks off antibiotic and the pain is slowly increasing again on my back in the kidney area. i cant sit touch or lie on my back. Its very uncomfortable. It also looks like I`m going to be missing another period this month. I did a hair analysis and they told me it showed strep in my kidneys. The month before i got the bladder symptoms i did have a really bad flu/throat thing the worse sore throat of my life. I feel like since then i have not gotten better, so can see a connection. But is it possible for that to be actually right if all the tests came out normal?
