My girlfriend has been suffering with abdominal pain for around ten days now. This is a pain all over her abdomen and tends to move from one area to the next, above and below the naval. She occassionally feels pain in the area of her kidneys too. There is no pain when urinating etc. She has also felt light headed lately, and described it at one point as feeling very limdly drunk.

She went to the Doctors last night and they suspected what they called a 'water infection'. Can someone explain this?

However they took a sample of her urine to be tested and dip stripped it finding abnormal levels of protein.

I suspect they were looking for kidney problems. Is this correct? She's only 22 and to be honest gets ill quite regularly. She was previously diagnosed with a kidney infection years ago. Her father is also diabetic.

Advice please. Thanks.
