I've been trying to overcome the effects of a cold and upper respiratory infection; basically, acute bronchitis. The usual methods have been used: rest, warmth, reduce vigorous exercise, sleep more, over the counter medicines, extra vitamins, lots of warm fluids, etc. Unfortunately, after 17 days, the problems are not resolving. A disappointing setback. I've had pneumonia twice in my lifetime, and bronchitis twice ... very unpleasant.
I taught yoga and felt pretty good. However, I have not taken my usual long walks in our cold weather or lifted weights.
Tomorrow, I will go and consult with a medical doctor.
