I ve had a long history of UTI s & I have MS. Wednesday night my bladder started to spasm & throb, thursday I used the bathroom & when I finished I noted a considerable amount of blood on the tissue! I wiped serveral times & it continued to show less & less blood but blood none the less! Since then, I had a culture that showed minimal white cells & did not culture out! I am having more pain, my ureathra feels like I have a broom handle there & I m sick as a dog! Trying not to throw up my lunch!! I also catherize & have been through this before where I would have 2 of 3 cultures done before an infection would show! I am now very limited on antibiotics! Someone please suggest something here, I m at a loss!!!
