Non-pitting Edema In Both Legs, Ankles And Feet. History Of Hypertension For Which Advised Lisinopril And Propranolol. Remedy?

the last 2 days I noticed non-pitting edema in both legs, most noticeable in the ankles and feet. thought it might be from a 4 hour car drive but realized it wasn't till the day after and late in the afternoon when it started. took a diuretic in the form of caffeine and did pass clear urine a couple of times but nothing significant. Did get up in the middle of the night to urinate but nothing major. No heart disease that I know of, had stress test in the past that was clear due to family history. I do have a history of hypertension which I take lisinopril and propranolol.
