Over The Past Few Weeks, My Left Leg -- From

Over the past few weeks, my left leg -- from around mid-calf to about 1-2 inches above my ankle -- feels heavier than the right. Typically, the left ankle is almost always swollen by the end of the day, but this does not seem to be affected by this tightness and heavy feeling in my leg. I have high blood pressure, but it is well controlled with lisinopril and HCTZ.. I have read the side effects of all the meds I am taking and none of them list this particular symptom. Do you need more information or can you give me your best shot in the dark?
