Hidden pain in the right side of the waist and pain in the eyes may be caused by kidney diseases such as nephritis or tumors, which need to be judged comprehensively, not relying on a single test indicator. When kidney disease such as nephritis or tumor occurs in the kidney, the right side of the waist may have symptoms of vague pain in the early stage. If accompanied by renal impairment, abnormal urinalysis such as hematuria and proteinuria, the metabolic balance of sodium and water is disturbed, and a large amount of fluid can not be eliminated through the kidneys, and stagnate in the body causing eye swelling and symptoms of pain. It also triggers high blood pressure, causing high intraocular pressure leading to fundus damage and eye pain. Ultrasound, CT, MRI of the kidneys and urine tests are needed for diagnosis and early treatment. In addition to the exclusion of kidney disease, other diseases should also be considered, and it is recommended to carry out examinations and treatments under the guidance of doctors.
