What could cause left lower backache and frequent urination especially at night?

Left lower backache and frequent urination, especially at night, may be caused by various medical conditions. Here are some possible causes:

1. Urinary Tract Infection (UTI)

A UTI is a bacterial infection that affects the urinary tract, including the kidneys, bladder, or urethra. It commonly causes symptoms such as frequent urination (especially at night), pain or burning during urination, and pain in the lower back or lower abdomen.

2. Kidney Stones

Kidney stones are hard mineral deposits that form in the kidneys. When the stones pass through the urinary tract, they can cause severe pain in the back, side, or lower abdomen. Frequent urination, especially at night, may also occur.

3. Enlarged Prostate (Benign Prostatic Hyperplasia)

Benign prostatic hyperplasia is a condition in which the prostate gland becomes enlarged, putting pressure on the urethra. This can lead to difficulty urinating, frequent urination, and pain or discomfort in the lower back, especially at night.

4. Gynecological Conditions

In women, left lower backache and frequent urination, particularly at night, may be associated with certain gynecological conditions such as ovarian cysts, uterine fibroids, or pelvic inflammatory disease (PID).

5. Musculoskeletal Problems

Sometimes, musculoskeletal issues like a muscle strain or injury, a herniated disc, or a misalignment in the spine can cause referred pain in the lower back that may be accompanied by frequent urination at night.

6. Kidney Disease

Left lower backache and frequent urination at night can also indicate underlying kidney disease, such as pyelonephritis (a type of kidney infection) or chronic kidney disease (CKD).

When to Seek Medical Attention

If you experience persistent left lower backache and frequent urination, especially at night, it is important to see a doctor to determine the cause. Some conditions may require specific treatments or further evaluation to rule out more serious underlying medical issues.
