Without clear information on your son's leg movements, a definitive conclusion is difficult. While leg shaking and propping up legs can be habits, they might also indicate lower limb varicose veins, which requires treatment.

Veins contain small valves that facilitate blood flow upwards and prevent backflow. When these valves weaken, blood can pool in the legs. This can lead to heavy, tired, tingling, or prickling sensations, especially after prolonged standing or sitting.

In such cases, the body often attempts to compensate. Leg shaking helps muscles contract, assisting blood flow upwards. Elevating the legs reduces pressure, making it easier for blood to return to the heart. These seemingly unconscious actions are the body's attempt to alleviate discomfort.

However, these are only temporary solutions. If you consistently experience leg fatigue in the afternoon, discomfort from prolonged sitting, or a constant need to change positions for relief, these could be early indicators of varicose veins. Should these signs recur, it is advisable to seek early medical consultation for diagnosis and advice.
