Blood clotting helps prevent excessive bleeding when a blood vessel is injured. Blood clots are life-saving. However, sometimes clots occur when they're not needed, and that can be troubling, especially if formed in the deep veins, also known as Deep vein thrombosis (DVT). If a DVT rupture from its position and travels to your lung, then it can cause a Pulmonary embolism (PE). The symptoms of blood clots range from DVT to PE. The symptoms of DVT may include redness or discoloration of the affected area; swelling, pain, and tenderness in legs and arms, and trouble breathing. The symptoms of PE may include- a dry cough, chest pain (sharp and stabbing), sudden shortness of breath or difficulty breathing; blueness in certain parts of the body (skin, lips); rapid heart rate; light-headedness or dizziness; fever, and anxiety.
