A pregnancy, or recently giving birth can cause blood clots to form in the legs, reports FamilyDoctor.org. Pregnancy increases the pressure in the veins of the pelvis and legs. The risk of blood clots from pregnancy can continue for up to six weeks after delivering a baby, reports MayoClinic.com.
Some people have chronic (long-term) problems after a clot due to damage done when the clot formed and partly due to the chronic obstruction from left-over clot, i.e. scar tissue. Post-thrombotic syndrome is one complication from a blood clot in the leg which results in long-term swelling and pain.
