Hi I m a 22 year old female and I ve had very bad pain in my lower right back/side area. Hurts when I yawn, cough, laugh, even deep breaths. I can t lay in any position to get comfortable because of the pain. I ve had this going on for about 2 weeks now and it s just getting worse I went to my doctor and she said there was no infection in my urine. But they found blood in my pee only because I am on my period. I m not sure what it could be, so I need some help!
