Hi, I Have Blood In My Stool Occasionally, Blood In

Hi, I have blood in my stool occasionally, blood in my urine(not a UTI ), severe back pain across my lower back above my hips which was relieved to a degree by 5 days of nitrofurantin 2x a day, nausea, vomiting, extreme stomach pain, especially at the end of my esophagus and trouble getting a deep breath and fatigue. I am a lightning survivor. Any suggestions? I have not felt good for months.
