Lower back pain with a full bladder?

User Profile
Lower back pain with a full bladder. Almost every morning when I wake up I have a dull pain on both sides of my lower back, around my kidney area. Sometimes the pain will wake me up early or in the middle of the night. It happens when I have a full bladder and once I use the bathroom my pain goes away after a minute or so, if not immediately. I only get this pain when I have a full bladder, and am having NO other problems with urination or anything like that. This has been going on now for approx. 3 months or more. I have been trying to limit what I drink before bed but I still usually have to get up early and use the bathroom.

Hi, welcome to the ehealth forum and I am glad to help you.
You seem to be concerned by the lower back pain with full bladder.
Your history and symptoms point towards the possibility of Vesicoureteral reflux(VUR) which is characterized by the retrograde flow of urine from the bladder to the kidneys. VUR, in your case, may be associated with urinary tract infection (UTI).
This reflux most commonly occurs in children, and it affects females predominantly. The majority of people with reflux are asymptomatic. However, one may have symptoms of a urinary tract infection and abdominal or flank pain with a full bladder.
Prolonged VUR can result in renal scarring, pyelonephritis (infection of the kidney), hypertension, and renal failure. Initial diagnostic work up include a complete history and physical exam, a urine analysis and culture, renal ultrasound, and a VCUG. Medical (antibiotics/ bladder muscle relaxant) and surgical treatments can be offered for those with VUR depending on the etiology and severity of the disease.
You must consult your doctor for the relevant investigations and definitive management as the same is not possible online.
Hope this helps. Take care.
