The clinical manifestations of moderate pain can be divided into the type of internalized evil toxicity, blood stasis and qi stagnation. The type with internalized evil toxins often presents with localized burning and pain that is fixed and does not move and becomes more intense when touched. The blood stasis type often presents with partially fixed pinch-like pain, a dark tongue and petechiae on the tongue. The qi stagnation type often presents with pain that is indefinite, tapping and swelling. What tests should be done for moderate pain? 1.Blood routine and blood sedimentation During the acute arthritis attack, there may be an increase in blood leukocytes and a rapid increase in blood sedimentation, but it is often less than 60mm/h. 2.Urinary routine In patients with a long course of disease, there may be proteinuria, hematuria and pusuria, and occasionally tubular urine is seen. 3.Blood uric acid measurement The majority of patients with acute attack have increased serum uric acid. 416µmol/L (7mg/dl) for men and 357µmol/L (6mg/dl) for women have diagnostic value by uric acid oxidase method. Blood uric acid levels may not be high if uric acid-removing drugs or glucocorticoids have been used. It can be normal in remission. 4.Uric acid measurement is not very helpful to diagnose acute arthritis, because more than half of the gout patients have normal urinary uric acid excretion. However, urine tests to understand uric acid excretion can be helpful in selecting medications and identifying whether uric acid stones are caused by an increase in uric acid. The 24h uric acid excretion in a normal diet male adult is at 3.54mmol (600mg/24h urine).
