hello, welcome to healthcaremagic
please make it a note to mention your age and gender with your question.
because the diagnosis of a disease can sometimes change only on basis of age/gender.
secondly, your symptoms do appear like that of stroke/
TIA. i would like to get following investigations done-
1. CBC with ESR
2. ECHO
3. ECG
4. Chest Xray
5. BP monitoring twice daily(as you mentioned you are on
lisinopril, so m guessing its most probably for
hypertension. and hypertension is the most common cause of a TIA.)
please visit a nearby ER asap as this could be something really severe.
hope this helps you.
I wish for your good health.
Please feel free to revert back in case of any more doubts/queries.
Thank you.
