What should I do if my feet are swollen? The first thing you should do when your feet are swollen is to move your swollen feet and see if there is any pain. If the foot is swollen and painful, there are two possible conditions: one may be trauma, bone damage or soft tissue damage, and the other may be gout. If there is trauma, there should be a history of trauma, and if there is soft tissue injury, there may be subcutaneous bruising and so on. If there is gout, the swelling of the foot may be more pronounced, and in severe cases there may be cellulitis with similar manifestations, that is, redness and fever. If the foot is swollen and not painful, just the surface red, even a little feverish feeling, or a slight pain, this condition may be a local cellulitis. If there is inflammation it is definitely necessary to reduce inflammation and also to carry out local treatment, but as long as there is a significant swelling and painful feeling, an X-ray examination should be carried out to see if there are any bone problems. If the color of the swollen skin of the foot is not different from that of the leg, and there is no fever, and the foot is only swollen, then elevate the affected limb to see if it will be reduced. If the swollen foot is significantly reduced after elevation, this condition is basically caused by venous return problems, such as poor venous valve function or muscle relaxation, which makes the venous return less smooth, or there are reasons for this, such as poor heart function or inferior vena cava obstruction. These problems need to be ruled out by corresponding examination. Most people may simply have poor venous return, which may have a characteristic that the swelling is lighter in the morning and heavier in the evening, and the swelling is more obvious in the afternoon and evening, and the swelling will be lighter in the morning when the feet are put up in a flat position after sleeping, which is basically the swelling of legs and feet caused by poor venous return in the lower limbs.
