<human>: my friend had a heart attack two years ago and died twice in hospital just the other day he said he went to stand up and there was a numb feeling in his leg so much so he had to grab on to table to stop him falling over im worried about him wot should he do
<bot>: Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would recommend going to the ER for a careful physical exam and some tests: - a resting ECG- a brain CT scan to exclude a stroke- a Doppler ultrasound of the cervical vessels to exclude possible peripheral embolism-complete blood count, blood electrolytes It is important excluding a possible stroke or an arterial occlusion in the leg as a possible cause of his symptoms. He may need urgent treatment. Kind regards,
