An unsteady walk that can be caused by pain, weakness or injury to the leg.

Rest. Ice the painful area. Compress the area with an elastic bandage. Elevate the limb with a pillow. Take ibuprofen (Advil, Motrin IB, others) or acetaminophen (Tylenol, others) for pain.

Seek emergency help if:

• The limp happens along with muscle weakness, numbness or tingling, or fever.
• The pain is constant, severe, comes on fast, or wakes a person up at night.
• The affected leg can barely move or stretch in the usual direction.

See a healthcare professional if:

• The limp lasts longer than a week and does not get better on its own.
• The limp limits a person's usual activities.
• A toddler or young child refuses to walk or stand.
