I Have A Prolapsed Bladder And I Had A Urine

I have a prolapsed bladder and I had a urine test about 3 weeks ago and had a lot of crystals in my urine no symptoms other than pressure between my legs. About 4 days ago I started having extreme pain in my right side and fells like something is stuck in my ureatha. Was at hospital this morning and only finding was large amount of blood in urine. I'm still in a lot of pain and can't pee normal any help ?
