I am a 17 year old girl who is having some unusual problems. For the past 2-3 months, I have been having lower and sometimes upper middle back pain , cloudy urine, dull and achy pains in the lower right abdomen/ groin area, headaches, fatigue , and little appetite. I do not have a burning sensation when using the restroom or any sharp pains. I did however have sharp pains about a month ago while using the restroom but the pain is no longer there. I have not been sexually active for over a year and have not had multiple partners. Two years ago I did have a bladder infection that turned into a kidney infection , other than that I have not had any medical problems. What could this be?
