Urinary tract infections: As urinary tract infections reach the kidneys through the urethra, they can cause low back pain, accompanied by frequent urination, urinary urgency, and painful urination. Once the infection is aggravated, it will inevitably lead to fever symptoms. Urinalysis can be a clear diagnosis.
2. Epidemic hemorrhagic fever: it is caused by hantavirus infection, with low back pain, accompanied by fever, body temperature above 39 degrees. It can also be accompanied by headache, orbital pain, skin rash and proteinuria.
