last night i started having a dull ache in my right lower back, coming and going every few mins or so. today it continued getting slightly more painful tonight and now on both sides. I feel that the pain is over my kidneys but have no other symptoms of urinary infection (although i do suffer cystitis quite frequently - approx 4-5 times a year).i just wondered if it is worth seeing my doctor tomorrow about this or notthanks
This could be a urinary infection, but the picture is not conclusive. It could also be discomfort from the colon. If the symptoms persisted you should consider doing a urinalysis. Its fast, informative and of low cost.  It is was positive for infection, you should proceed to urine culture to detect the causative bacteria and the most effective antibiotic, and see your doctor. Blood sugar and renal ultrasound are also recommended to look for the cause of these frequent infections. Hope this helped with your concerns. For any further questions please feel free to ask.
