Hello and thank you for asking HCM. I have read all your symptoms and i will explain everything that you need to know. For my experience,i think that you have an urinary tract infection (UTI), probably a cystitis (infection of your bladder).Bacteria that enter through the urethra and travel into the bladder cause bladder infections. Our urine is sterile,what it means is that there are no cells like bacteria or other type of pathogen microorganisms. In the moment when these bacteria invade our UTI, an inflammation is created. Our body starts fighting these bacteria that most of the time these bladder infections are caused by Escherichia coli.This is the reason why you have these symptoms, the burning sensation, the lower back pain,and the white sediment and cloudy urine. Also you might have the urge to urinate, urinate a small amount each time,urinating more often than usual or even bloody urine. Lucky for us it is easy to cure this infection,before it spreads at your kidneys. If i was your doctor i would start you on antibiotics, the fluoroquinolones are the best in this case so i suggest you have a check up with your family doctor to get the prescription with antibiotics and i would suggest to do a urine test/culture to confirm the diagnosis. I would advice you to do this diet during the time that you are treated for this infection: -Have plenty of liquids. This way our body will try to flush the bacteria with the urine and get cleaner.Drink cranberry juice daily if possible. -Use orange juice because Vitamin C helps your immune system to fight the infection -Use chamomile tea,or Marshmallow Root Tea The use of these kind of tea,and the cranberry juice are natural antiseptics. They help to fight the infection,also they prevent getting one. If you have any other question,feel free to ask me. Wish you good health. Dr.Endri Katro
