Achilles Tendinitis
The Achilles tendon is a band of tissue that
joins the muscles in your lower leg to your heel. Running long distances can
strain this tendon and cause it to swell, resulting in pain and friction.
Severe tendinitis can even cause a rupture of the tendon. Running long
distances uphill, increasing your speed, or adding hills or stairs to your
routine can trigger Achilles tendinitis and swelling of the lower legs.
Fluid Buildup
Because you are in a prolonged upright
position when running long distances, gravity can cause fluids to build up in
the tissues of your lower legs, resulting in swelling. This is called
peripheral edema. In addition, problems with your circulatory system, kidneys
or lymphatic system can contribute to fluid buildup and cause swelling in your
lower legs after jogging a long distance.
Inflammation Disorder
Running-related lower leg inflammation can
occur as a normal immune system response to a disorder or injury. For example,
running long distances can trigger inflammation and pain if you suffer from
conditions such as gout, osteoarthritis or an inflammatory joint disorder like
rheumatoid arthritis. In addition, swelling can develop if you run long
distances while suffering from a wound or infection on your lower leg.
