I am 69 years old, female and have many, many health issues. My doctor has recently asked me to have a colon test. Should I be worried? I thought my kidneys were acting up ~ ~ lower back pain, front abdominal pain, weak urine stream, pain when urinating, frequent urination, and I do have damage to my left kidney due to my diabetes. Would all these symptoms be present do to a colon problem. I m more worried about my kidneys !?!?
