Low sodium

Low sodium ...Ramipril.cloperdogral,lansoprazole are what I take ,after my stroke 2years ago. Then the doctor picked up on low sodium levels after blood test. That was in Feb. Just had my 13th blood test and I am thoroughly fed up. No further on with diagnosis,but I am wondering if anyone else has had this problem. The doc told me not to take my blood pressure med,Ramipril ,but when I went for BP check at doctors it was 168over 94! 

Previously ,I had felt so well and HAPPY.Now I am anxious and worried..Please help.
