I have a genetic blood disorder with no name. It causes an imbalance in my protein s and c. My hematologist says it is similar to Laden Factor -5. I have had 1 DVT previously and I currently have my second one. My Mother is is an incapacitated stroke victom fron this condidtion. I have a history of high blood pressurs.At the time of my first DVT ; my family Dr had me on Lisinopril (with a diuretic). That Dr subsequently died and my new Dr took me off Lisinopril (w/diuretic), because he said with my blood - the diuretic lead to the DVT. He put me on Bystolic. The Bystolic never consistantly controlled my BP. I then tried a calcium blocker..did not control BP. I then went back to Lisinopril (without diuretic), it controlled my BP..but now after 2 months back on Lisinopril my DVT is back. Is it the Lisinopril..or just my blood disorder? Should I try a different blood pressure medication?
