### Patient: Doctor, I've been experiencing poor circulation in my legs, feeling cold often, and even swelling in my legs. Recently, I've also been coughing up blood. What could be the issue?
### Doctor: Based on the symptoms you've described, it's possible that you have peripheral arterial disease. This condition occurs when there is a blockage or narrowing of the arteries in your legs, which can cause poor circulation and lymphedema. The feeling of coldness could be a result of reduced blood flow in your extremities. And, hemoptysis, or coughing up blood, may occur as a result of the reduced blood flow in the lungs.
