<s>[INST] I have diabetes, dark urine, leg cramps, rapid pulse at times, metallic taste, sometimes I feel weak, flank pain and hip pain.  I have had dark urine for a couple of years and have been prone to urinary track infections.  I had my last diabetic screening about a year ago and there were no signs of kidney problems at the time.  The metallic taste has been going on for about a year along with the mild leg cramps.  I have a doctors appointment in 4 days and I am out of town.  I had the flu about a month ago and I was taking meds that had warnings for the kidneys.  I did not realize that metallic taste and muscle cramps were signs of kidney problems until I started checking on line.  I am worried, can I wait until I get home to see the doctor.
