Stress Thallium Conducted On 11th January 2016 Is Normal. I

Stress Thallium conducted on 11th January 2016 is normal. I was done with PTCA on 25th July 2012. Get frequent pains while walking and climbing inclined places. Also I am brisk and can walk even 2 kms on most of the days. I am on medicines like antiplatelet, blood thinner, etc.

Should I worry or stop worrying........kindly advise doctor.
