I've been having serious pain in my lower abdomen sharp jabbing pain, in my lower back as well. I thought I had a kidney infection. When I went to the hospital 4 days ago, they told me its a uti. So I've taken the meds prescribed and I can't tell any changes at all. The pain has gotten worse in my abdomen especially on the right side. The only thing that the Dr took was a urine sample, could this be something besides uti?
