Achy arms and legs have several various causes. Often, it can be overtaxing the limbs with excessive physical activity: sports, moving furniture, long walks. This can usually be fixed with simple rest or massage. If, however, this problem persists, you may have a problem with poor circulation, causing insufficient blood flow in those limbs to keep them from relaxing properly when at rest.
Besides poor circulation, there may be a fluid buildup in the joints, causing additional, and unnecessary strain on your muscles.
