Clinically, patients with right-sided facial swelling without pain generally have the following common causes: a. Patients with chronic kidney disease or nephrotic syndrome may have blocked urinary excretion or lost a large amount of protein in the body, thus causing water in the body to accumulate in the lax tissue of the face, resulting in facial swelling and no obvious pain. At this time, patients need to have blood sampling to improve kidney function, kidney ultrasound and other examinations to improve kidney function, strengthen diuresis, replenish protein and promote water metabolism in the body to reduce facial swelling after clarifying the cause. Secondly, female patients with allergies may experience obvious swelling on the right side of the face when they apply more cosmetics. At this time, patients need to remove cosmetics from the face as soon as possible and take oral loratadine, paracetamol and other drugs to reduce allergic metabolic reactions in the body, which can improve the swelling of the right side of the face.
