Blood Clots
Arms and Legs
When a blood clot forms in one of the deep veins in your arm or leg, way beneath your skin's surface, it could be something called a deep vein thrombosis (DVT). That's dangerous because the clot could travel to your heart or lungs.
You're more likely to get DVT if you've haven't moved around for a long time, say after surgery or during a long plane trip. Get medical help right away if you notice any of these symptoms:
Swelling: This can happen in the exact spot where the blood clot forms, or you may puff up on your entire limb.
Change in color: You might notice that your arm or leg takes on a red or blue tinge, or gets warm or itchy.
Pain: As the clot gets worse, you may hurt or get sore. The feeling can range from a dull ache to intense pain.
Trouble breathing: If this happens, it could mean that the clot has moved from your arm or leg to your lungs. You may also get a bad cough, and might even cough up blood. You may get pain in your chest or feel dizzy.
Deep vein thrombosis, or DVT, is a blood clot that forms in a vein deep in the body. Most deep vein clots occur in the lower leg or thigh. If the vein swells, the condition is called thrombophlebitis. A deep vein thrombosis can break loose and cause a serious problem in the lung, called a pulmonary embolism.
Lungs
A blood clot in your lung usually starts out in a deep vein in your arm or leg, then breaks off and travels to your lung. When this happens, you get what's called a pulmonary embolism, an extremely dangerous condition.

Brain
Blood clots here may be caused by fatty deposits in the walls of the blood vessels that bring blood to your brain. Or sometimes, they may form because of a blow to your head that leads to a concussion.
In other cases, a clot that starts out in a different part of your body, like your chest or neck, might enter your bloodstream and travel to your brain, where it can cause a stroke.
Caused when there is a cut in the skin and blood rushes to heal the wound.They can also form when they aren't needed and cause a heart attack or stroke.
