Back pain is not necessarily related to elevated blood uric acid, and even if there is a prolonged period of elevated blood uric acid, it does not necessarily produce the corresponding clinical symptoms. Only when elevated blood uric acid is not metabolized in the body and accumulates in certain areas can it induce the corresponding clinical symptoms. Clinically, the most common is the accumulation in the joints of the big toe, ankle or knee, which will produce corresponding swelling and pain, but rarely cause lower back pain, even though the blood uric acid can accumulate in the kidneys, causing damage to kidney function. Lower back pain is more commonly associated clinically with prolonged sitting, prolonged standing, bending, and excessive exertion and strain, causing diseases such as myofasciitis of the low back, lumbar muscle strain, or lumbar disc herniation. In addition, the pain produced is related to blood uric acid, and there is a typical feature that there is drinking and eating seafood, hot pot, animal offal, soy products, etc. before the pain, and the basic pain gradually disappears after dietary control.
