What causes a sore kidney?

A sore feeling in the kidney area is often due to a urinary tract infection (UTI) or back muscle strain. Please rest well and drink plenty of fluids. If the pain is accompanied by fever or burning urination, please see a doctor.

Sometimes a dull ache in the lower back is mistaken for kidney soreness, which can be due to poor sitting posture and lack of spinal flexibility. Gentle stretches and staying hydrated help a lot. However, if it's an internal ache, a doctor's checkup is necessary.

My daughter had a similar soreness and we found out she had a mild kidney infection from a neglected UTI. Please do a simple urine routine test, it costs very little and gives a clear picture. Don't let them hold their urine for long hours.

Kidney issues should never be self-diagnosed or ignored, as infections can spread quickly. If the soreness is on one side of your upper back, it could be a stone or infection. Please go to a hospital and get an ultrasound done for proper safety.

Usually, it is either dehydration or a minor stone trying to pass. Drink at least 3 liters of water daily and avoid too much salty food or spinach for a few days. Getting a basic kidney function test (KFT) from a local lab is a very practical way to be sure.
