Paying attention to your body.......your body already has alerted you. I feel if the PCP is willing to diagnose TIA then they should be proactive in the prevention of another occurrence. Low dose ASA at the very least... Just my two-cents. I was placed on warfarin after a declared TIA but questionable TEE results years ago. Perhaps a little overboard with the medication but at least proactive. Could probably come off it but after my history no physician has the appetite to take the chance!
