Some individuals end up with swollen legs after a running session. It is important to note that running can result to slight damage to the body. While running, the legs endure continuous pounding as they support the body weight. After running, some develop swollen legs.
What are the causes of swollen legs?
- Injuries – sustaining any damage to the muscles, bones, ligaments or tendons in the lower leg can result to swollen legs. While running, the bones, muscles, tendons or ligaments in the legs can be damaged. When an injury occurs, the inflammatory response of the body takes in excess fluid to the site of injury which results to swelling.
- Blood clots – even though blood clots are not likely to develop, the formation of a blood clot can lead to swollen legs. A clot can prevent blood from moving out of the leg and results to redness, swelling and soreness. Although running will not cause the blood clot, running with a blocked vein can be painful and considered dangerous.
- Chronic venous insufficiency – various vascular conditions can lead to swollen legs after running. This condition arises once the impaired leg veins could not adequately return blood to the heart. As an outcome, the blood accumulates in the lower legs which causes the legs and ankles to swell.
- Fluid retention – gravity causes fluids to buildup and settle in the legs, especially during prolonged periods of standing or sitting. Running requires the legs to support the body weight for an extended time. While in an upright position, the gravity draws the body fluids into the legs which results to swollen legs.
- Cholinergic urticaria – this condition causes the legs to break out into a rash with small-sized engorged bumps. If several are present, the legs start to feel significantly itchy and swollen.
