When a blood clot forms in the lungs or heart, the symptoms might be similar to that of a heart attack. You might notice pain in the chest area, have difficulty breathing and experience tenderness in the jaw or neck. There could also be back soreness and pain in the arms.

Every so often, blood clots might produce an array of other symptoms, including a red rash with spider web type lines on the knees and wrists. When there is a significant drop in platelets (blood cells needed for adequate clotting,) you might experience episodic bleeding from your nose and gums. It's also possible to bleed into your skin. That would be visible as bits of tiny red spots. When a blood clot inhibits blood flow to the brain, there is a possibility of migraine headaches and seizures.

A blood clot can result in unusual and frightening symptoms. They have been known to include a sudden loss of hearing, depression or psychosis and loss of memory. In rare instances, uncontrollable jerking of the body, can occur.
