A blood clot has the appearance of purple or red. It is usually in the shape of a lump. Blood Clots can be painful, hot to touch, and can cause reddish streaks going up or down from the clot.
A blood clot can cause swelling, inflammation and pain. However, in many cases, a blood clot may occur without any obvious symptoms. If the clot breaks off and travels to the lungs, this is known as a pulmonary embolism and can be life threatening.
This may produce shortness of breath, dizziness, confusion and severe pain. You can find more information here: nlm.nih.gov/medlineplus/ency/article/001....
