In brief: See below
If the ct chest and us of legs are negative, you don't have dvt/pe.
There must be another reason for the d-dimer to be +. Is your kidney function ok? Have you had a recent injury, surgery or something else that involves blood-clotting? How + is the test? You can consult a hematologist, or just watch it and treat the asthma. Talk to your doctor. Good luck!

In brief: Venous incompetence
D dimer is a non-specific test meaning it doesn't really tell us anything espeically with a normal ct which would have picked up a pulmonary embolus.
The most common cause of ankle swelling especially in obese people is venous incompentence. The valves in your veins aren't working and that leads to venous pooling in your ankles and feet.
