Swelling in an affected limb after a stroke

Swelling develops when the affected arm or leg cannot move for a long period of time. A large amount of swelling:

• Causes decreased blood flow in the limb, which increases your chance of developing skin sores (pressure sores).
• Limits movement of the limb, which increases your chance of developing stiffening of the joint (contracture).
• Causes pain and discomfort in and around the swollen tissues.

Some tips to prevent swelling in your affected arm or leg include the following:

• Elevate the affected arm or leg. If your arm hangs down at your side for long periods of time, you will have more swelling in the arm.
• If swelling develops, massage your arm or leg and wear elastic stockings or gloves.
