There is still a bit of mucus in my lungs left over the surgery, but the exercise is definitely helping it to clear, although with Mucinex DM.
After I finished treadmilling, my blood pressure was 114/61, pulse 94. Obviously, the combination of calcium channel and beta blocker medicines is part of what is keeping my blood pressure low. I am hoping that as I restore my cardiovascular conditioning, and as everything finishes healing, I will be phase these down.
I would say that my greatest remaining discomfort is the mucus in my lungs that hasnt quite cleared.
