I am 4 months pregnant with twins. I recently took a cross-country flight and wore compression hose to help prevent swelling. After the flight, however, my right leg / ankle were quite swollen (but not red or hot or painful to the touch). The swelling went down but the leg remained achy for a few days.
On 2 occasions during those initial few days after the flight, I had a sudden onset of lightheadedness, shortness of breath, racing heart, and a terrified feeling that something was very wrong. But the symptoms passed within about 5 minutes.
I am wondering if these were related to the leg swelling and if it was possible that I had a DVT that traveled to my lungs, but was not big enough to cause any *major* problem? Is it possible for such a thing to resolve on its own? Or if it really was a DVT / PE, is it lying dormant but can break off and cause a problem in the future?
