Sore and sleepy legs and weakness are usually often found in the following situations: First, patients who need to be bedridden for a long time due to illness suddenly get out of bed on their own. At this time, due to the lack of sufficient exercise of the lower limb muscles, there will be different degrees of atrophy. When walking, patients will have symptoms of soreness and weakness of the lower limbs. It is recommended that patients exercise their lower limb muscles according to their strength and in a gradual manner to avoid falling and causing additional complications during activities. Second, just after doing strenuous exercise or fitness situation, there will also be the performance of leg soreness and weakness. It is mainly because a large amount of lactic acid accumulates in the blood vessels of the lower limbs, causing a decrease in muscle contraction function and weakness performance. Third, patients with severe varicose veins in the lower limbs, because the blood in the varicose vessels cannot participate in the systemic blood circulation, the metabolic wastes in the vessels accumulate in the lower limbs, which will cause soreness and weakness. Patients with severe symptoms are even accompanied by the formation of local chronic ulcers.
