When the valves become weakened or damaged, blood can collect in the veins. This causes the veins to become enlarged. Sitting or standing for long periods can cause blood to pool in the leg veins, increasing the pressure within the veins. The veins can stretch from the increased pressure.

Are you suffering from backache?
Sitting all day weakens the upper back and core muscles, making the shoulders work harder to maintain posture. Overuse of the front shoulder muscles (pectorals) and underuse of the upper back (trapezius, rhomboids) cause imbalances, leading to pain.

Low estrogen, high cortisol, low thyroid hormones
Estrogen helps reduce inflammation; when it drops (like in menopause), joints feel stiff and achy.
High cortisol (stress hormone) can increase muscle tension and pain.
Low thyroid hormones slow metabolism, leading to muscle stiffness and weakness.
