Symptoms

Signs of edema include:

• Swelling or puffiness of the tissue directly under your skin, especially in your legs or arms
• Stretched or shiny skin
• Skin that retains a dimple (pits), after being pressed for several seconds
• Increased abdominal size

When to see a doctor

Make an appointment to see your doctor if you have swelling, stretched or shiny skin, or skin that retains a dimple after being pressed (pitting). See your doctor immediately if you experience:

• Shortness of breath
• Difficulty breathing
• Chest pain

These can be signs of pulmonary edema, which requires prompt treatment.

If you've been sitting for a prolonged period, such as on a long flight, and you develop leg pain and swelling that won't go away, call your doctor. Persistent leg pain and swelling can indicate a blood clot deep in your vein (deep vein thrombosis, or DVT).
