My blood pressure is 124 over 86 but my haertrate is over 100 even at resting time. is this a concern?

That's high: The most common reason...lack of cardiac conditioning...Start with a complete cardiac evaluation. An in person visit with a Cardiologist who can perform a monitored Exercise Tolerance test...if declared HEALTHY an exercise program which should be supervised if possible at the beginning.By the way, The cardiac evaluation should include Thyroid tests Hope this is helpful Dr Z
