I am a 68 years old female. 2 years back I had a stroke and then treatment included RF ablation. I am on BP and sugar medicines. Sugars are <150 mostly. For the last few weeks my BP has been fluctuating and going as high as 180/98. I saw a doctor who asked me to increase my BP medicine and add"telma". After that I started feeling v weak. I have discontinued it since yesterday but still feel weak. Sometimes I also get v dizzy and want to sit immediately. Can you please suggest what could be the issue.
