I'm a 20-year-old female with no previous history of kidney problems. I have a family history of several different types of cancer, high blood pressure, diabetes, and nephritis. I have not been diagnosed with any of these diseases so far. I have recently quit smoking (about 8 months ago), and I am currently taking no medication, not even aspirin or birth control. I drink about 6-10 glasses of water per day, and 1-2 cups of coffee. I have about 2 alcoholic beverages once a week. I am not pregnant.
For the last 4 months, I have been experiencing gross hematuria with extreme lower back pain. Sometimes this is accompanied by a deep, chesty cough, as well. Often, the pain is so severe I cannot move or get out of bed for several hours. I was given antibiotics for a UTI, which had no effect. I had blood work, an X-ray, and a CT scan (without contrast), which all indicated that I do not have kidney stones. However, I have continued to suffer from the above-mentioned symptoms - about every 3 weeks, I experience one of these episodes 2 or 3 times a week, usually very early in the morning. I have been to 2 doctors, but neither of them have given me a particular diagnosis or an effective treatment, but both seemed fairly certain that it is kidney-related.
Am I overreacting? Could there be causes for these symptoms other than a UTI or kidney stones? I'm very concerned, and I would very much like to know what is wrong with me.
Thank you for your advice.
