My mother (58+ Y) is under treatment for Hypothyroidism & Hypertension. She used to have controlled BP (110/70 - 130/80) & sugar (FBS - 97) till a month back. Over last few days she is very tensed due to health issues at home. Today afternoon she suddenly felt 'chakkar' lost vision for 3-4 minutes & was about to fall down from the sitting position. Her speech was also not very clear during those 3-4 m. We also observed her left hand is shaking for that time. However, she was back to normal activities within 5 minutes. Is this an emergency? What should be our next steps?
