Hi, I had blood tests and a urinalysis done about 2 weeks ago; however, I have a pretty severe pain (mostly hurts to touch) on my back below my ribcage. I am scared it is a kidney problem. Here are some of my results--the test was done after fasting for 12 hours.

BLOODS
UREA: 3.7 (3.0-8.0)
CREATININE: 97 (55-110)
SODIUM: 144 (134-144)
POTASSIUM: 4.7 (3.5-5.5)
CHLORIDE: 106 (98-108)
BICARBONATE: 32 (22-31)
GLUCOSE FASTING: 5.2 (3.9-5.5)
CALCIUM: 2.59 (2.12-2.62)

DIPSTICK
GLUCOSE: Normal
KETONES: Negative
SP. GRAVITY: 1.021
BLOOD: Negative
pH: 6.0
PROTEIN: Negative
NITRITE: Negative
LEUCOCYTES: Negative
BILIRUBIN: Negative
UROBILINOGEN: Normal

Any help would be appreciated as I am scared out of my mind. It hurts to touch but I had an ultrasound of the gallbladder about a month ago and they checked my kidney--they LOOKED normal. My blood tests are 2 weeks old--can anything develop that quickly? Anything serious at least?

Thanks in advance.
