2.Pain in foot and calf
Pain in the foot is a serious effect of blood clots. Blockages hinder proper blood flow to these areas and the lack of oxygen to the foot leads to major discomfort. In the calf, a condition known as deep vein thrombosis can create harsh pain that makes walking difficult and arising from a sitting position painful.
also Back pain might not seem like one of the likely blood clot symptoms, but it can be an indication that a blood clot is present in the pelvic area or in the inferior vena cava, which is the major abdominal vein. These types of clots can result in permanent damage if not treated, as they cut off blood to the extremities.
