I am having painful pressure while I urinate constant cramping in my lower abdomen left side, lower back, and pelvis. My urine is cloudy.?

Pyelonephritis . The symptoms are a bit concerning for a urinary tract infection, possibly involving the kidney (pyelonephritis). I would recommend a visit to a physician. A course of antibiotics may be needed. If you develop any fever, chills, or vomiting, a visit to the er would be better. Hope that helps.
