I am a 25 year old female with no medical insurance. Two weeks ago (on a Sunday), I noticed symptoms of a UTI (pressure, frequent urination) so I immediately began treating it with cranberry capsules (triple strength, 2 3x's daily), drinking lots of water and getting vitamin c. The symptoms went away within a few days and on that Friday I decided to try and work out a little, but had to stop since it was too intense (advanced stuff I shouldn't have done). On Saturday I noticed some back pain. Over the next few days, I was slouched over trying to fix a computer, helped carry a flat screen tv in for my disabled father in law and also shoveled snow.
A little over a week later, my mid to lower back hurts, but feels like it's getting better. The pain could best be described as a dull ache and maybe a 2 on a pain scale of 1-10.
Naturally I am worried that my UTI could have possibly evolved into a kidney infection. I do not have any nausea, fever, chills or problems when urinating. I've used the AZO test strips the past two days and the results have been negative (they test Leukocyte (white blood cells) and Nitrites).
So my question is this: does this sound like back pain or a possible kidney infection? I'm just really paranoid because I don't have insurance.
Thank you in advance! I appreciate any information you all can provide!
