Dehydration can increase BUN... If this was done fasting, you might have not been drinking water enough.
Many drugs can increase BUN too:

The most common one is the family of thiazide diuretics which are very commonly used for blood pressure ..example hydrochlorothiazide.
I would get tested for gout, since the BUN ratio is elevated.
Long term gout can affect the kidney, as well as cause pain in the feet and elsewhere.
