Given the data you provided (measured high blood pressure, previous history of pulmonary embolism, family history of hypertension, swelling on hands and feet and daily headaches), you are highly likely experiencing hypertension.
The threshold for the systolic pressure is 140 mm Hg and for the diastolic pressure it is 90 mm Hg. These thresholds are even lower for patients with other accompanying conditions such as diabetes mellitus, for example. Since you reported measured blood pressure of 148-91 to 155/105, the criteria for hypertension are met.
You might want to ask for another opinion by another doctor. Changes in lifestyle, reduced salt intake and exercises might be recommended. If this does not help, the doctor might recommend antihypertensive drugs.
The pulmonary embolism might be related to the arterial/venous malformation in your pelvis. Actually, any place where the blood flow is changed from laminar to turbulent creates an environment where blood clots might be created. If these blood clots are detached, they are called emboli and might cause an embolism.
