I m 29, I think about 5 11, 308lbs, and I ve never had urinary problems, but I ve recently got diagnosed with a uti, I have taken Cipro and Keflex for the infection, and now it feels like something it stuck in my urethra and every time I urinate it feels like I have to push, like my body is making me do it. I also have a kidney stone and I don t know if that may be causing the problem with my urination.
