### input:
i BELIEVE I HAD A TRANSIENT ISCHEMIC ATTACK YESTERDAY AND AM STILL EXPERIENCING SOME TINGLING/NUMBNESS IN MY LEFT SIDE. EVERYTHING I READ INDICATES YOU SHOULD GET TREATMENT IN THE FIRST THREE TO FOUR AND A HALF HOURS. SINCE IT S OBVIOUSLY WELL PAST THAT TIME, I FEEL LIKE A TRIP TO THE EMERGENCY ROOM IS NOT BENEFICIAL. IS THIS SOMETHING I SHOULD MONITOR OR IS THERE TREATMENT THAT CAN BE DONE IMMEDIATELY TO PREVENT FUTURE TIA OR STROKE?

### output:

Hello! Thank you for asking on Chat Doctor! I would like to explain that a transient ischemic attack lasts less than 24 hours and normally less than one hour. Your symptoms may be related to a transient ischemic attack or a stroke. I recommend you to go to the ER and consult with a neurologist, perform a careful physical examination, blood pressure monitoring, routine blood test, kidney and liver function tests, blood electrolytes, ECG and a Doppler ultrasound of the cervical vessels). A brain CT scan or MRI scan if possible is necessary to establish the diagnosis. A transient ischemic attack must be monitored in the ER as an alarm sign for future strokes. The cause of this event should be investigated (by a detailed check-up), in order to evaluate the risk for future strokes and start the proper therapy to prevent this. Hope to have been helpful! Greetings!
