What primary issue can be alleviated by the use of compression stockings?

The primary issue that can be alleviated by the use of compression stockings is swelling and pain in the legs and feet. Compression stockings work by applying graduated pressure to the lower extremities, which helps to improve blood circulation and reduce the accumulation of fluid in the tissues. This is particularly beneficial for individuals who experience conditions such as chronic venous insufficiency, edema, or post-surgical recovery, as it helps to alleviate discomfort and promotes better venous return to the heart.

While other options present conditions that may potentially be influenced by similar factors, they do not directly relate to the primary function of compression stockings. For instance, low blood pressure is typically not treated with compression therapy, and while improving circulation might have ancillary effects, compression stockings are specifically designed to manage swelling and pain. Skin infections and nerve damage may require different forms of treatment and are not directly addressed by wearing compression stockings. Thus, the main role of these stockings lies in mitigating swelling and discomfort, making that the most accurate response.
