A tight leg can stem from various causes, ranging from simple muscle strain to underlying medical conditions. Let's explore some common reasons.
Common Causes of Tight Legs

Muscle Strain or Overuse: Sleeping awkwardly, intense exercise, or prolonged periods of sitting (like at a computer) can all lead to sore, tight muscles. This is often due to muscle fatigue and a build-up of lactic acid. [Source: Sleeping in an awkward position, exercising too hard or sitting at a computer all day can all lead to sore, tight muscles.]
