Aching or heavy legs - Advice from experts
Causes of aching or heavy legs
The sensation of heavy or aching legs is related to a loss of firmness and elasticity of the vein walls, which causes a slowing of blood circulation in the veins. Because of this, the veins dilate and blood pressure increases. Valves, the small flaps that normally keep blood from flowing back down the leg veins, have difficulty maintaining this pressure and progressively become deficient. Resistance to leaks weakens and blood stagnates in the lower portion of the veins, which further impairs vein walls. A vicious circle takes hold.
