The common causes of double kidney pain include pyelonephritis, lumbar muscle strain, kidney stones, prostate diseases, etc. Most patients with pyelonephritis are caused by systemic infection of blood flowing to the kidney, or retrogressive infection of bacteria in the urinary system, which will lead to congestion, redness and swelling in the renal pelvis and around the renal pelvis, thus causing pain in both kidneys. Lumbar muscle strain often occurs on both sides, mainly due to long-term hard work or lack of attention to rest and other reasons, resulting in excessive fatigue of both lumbar muscles, and pain in both kidneys will occur over a long period of time. Kidney stones, especially uric acid stones, can cause stones in both kidneys. During the stone activity, it is easy to cause pain in both kidneys. This pain is severe colic, which is unbearable for ordinary people. Prostatitis is the most common cause of bilateral kidney pain due to prostate disease, because this inflammation may also cause bilateral low back pain and bilateral kidney pain.
