Well, normally cloudy urine and strong smelling urine signal an infection. I had one a couple of years ago and had no idea I even had one until my doctor told me...I didn't have any symptoms except cloudy and strong smelling urine.
Are you by any chance dieting? Many people on the Atkins diet will have your symptoms from all the protein they're ingesting. Different foods can cause your urine to smell strong, such as asparagus, but it's the cloudiness that would concern me. If you haven't changed your eating pattern or started any new medicine or vitamins, you may want to have your doctor do a quick check. Urine smell isn't usually something to worry about, but cloudiness is as it could be blood if you do indeed have an infection.
Let us know how you are, ok?
