I am on 10mg lisinopril and 12.5 of a Diuretic. My fingers have been swelling up so bad to the point I had to have my rings cut off. My doctor doesnt seem concerned, just gave me another Diuretic 12.5 to take it when I swell up again. Will that lower my BP a lot or make me fee weird? I never heard of anyone taking that much unless they have CHF.
