A TIA can not be excluded either, considering your past medical history for stroke. Coming to this point, I would recommend going to the ER for a physical exam and some tests: - a brain CT scan or MRI - an EEG- complete blood count- a resting ECG- blood electrolytes- fasting glucose- kidney and liver function tests. Meanwhile, it is necessary to closely monitor your blood pressure and heart rate values. Hope you will find this answer helpful!Kind regards! </s>
