Litmus Test

There are 17 steps between the dining/living room floor in our house and the bathroom and bedrooms upstairs.

When I had BOOP, I couldn't make it up the flight of stairs without stopping midway, because my lungs needed to take in more air.

When I had BOOP and I was on prednisone, I had trouble getting up the stairs. I don't know why.

Now, I am coming off the prednisone, and I have trouble going up the stairs because my legs are so weak. Today I rode my bike, but it was arduous, even for 15 minutes. How different from a few weeks ago when I rode everywhere on Fire Island.
