Hi I’m 34 and For 2 months now I have been have horrible pain my spine and lower back... when I think I have to urinate I have to push every time and makes me cry because I get stabbing pain my lower back and lower abdomen.. gone to an Er they just did blood work a couple of things were abnormal but they said urine was fine when the test showed WBC and something else. I gained weight than lost a lot I get diarrhea than it turn into constipation... sometime I will be so nauseated for days that I end up throwing up a lot what’s wrong
