Local tenderness

Introduction From an anatomical point of view, the bone plate is very thin, the skin covering this part is also very thin, and the periosteal sensory nerve is also rich, so it is sensitive to the touch pressure, and tends to produce obvious tenderness. The case of tenderness is more common in cases where local inflammation stimulates muscles or nerves.

Cause

1 superficial phlebitis caused by chemical stimulation, intravenous injection of various irritating solutions, such as: hypertonic glucose solution, various antibiotics, hydrocarbonating agents, organic iodine solution, etc., can be injected into the superficial vein The chemical stimuli cause a rapid formation of thrombosis in a wide range of lesions, followed by a significant inflammatory response.

2 catheter for continuous infusion often causes direct damage to the vein wall to thrombosis, and rapid inflammatory response. It is common in critically ill patients such as extensive burns, severe trauma and major surgery.

3 When the varicose veins of the lower extremities belong to the genus of the saphenous vein or the small saphenous vein, the venous blood stasis lags the skin of the foot. Often due to nutritional changes, chronic infection can cause venous venous inflammation caused by hypoxia and inflammatory damage in varicose veins.

If tenderness occurs, it should be highly valued and promptly go to the hospital for treatment.

Abdominal local tenderness: abdominal inflammation, such as mild appendicitis, pancreatitis.

Abdominal diffuse tenderness: extensive inflammation such as peritonitis.

Chest wall tenderness: pleurisy, sternal fractures, etc.

The site of tenderness often suggests lesions associated with the abdominal organs.

Differential diagnosis

Differential diagnosis of partial venous tenderness

Thrombophlebitis is mainly divided into two types: thrombotic superficial phlebitis and thrombotic deep phlebitis. The former is divided into limb thrombotic superficial phlebitis, superficial thrombophlebitis of the chest and abdominal wall vein, and migratory thrombosis. Phlebitis and so on. The latter is divided into calf muscle venous plexus thrombophlebitis and iliac vein and iliac vein thrombophlebitis. Clinically, it should be carefully diagnosed according to different characteristics.
