Blood clots can form in your legs for many reasons including, prolonged bed rest, limited movement, hospitalization, or injury. Whatever the reason they are always dangerous.
A few signs of a blood clot are chronic pain and persistent swelling. If you are experiencing either of these symptoms contact a doctor immediately. When blood clots are caught early they can be treated with medication fairly easily. If the symptoms are ignored the clot could end up dislodging and traveling up the bloodstream to the lungs causing a Pulmonary Embolism (PE), which can be fatal. The warning signs of PE are shortness of breath and sharp pains on deep breaths.
Stay active, maintain a healthy diet and see a doctor regularly. These are all ways that can help you prevent and catch blood clots before the turn deadly.
