With respect to workout, cardio with a bike or running, or weight training, muscle soreness and fatigue is appropriate and a normal physiologic response.
However, joint pain in the knee, shoulder, ankle, or what have you, is not normal.
For patients of any age, my motto is don’t push through pain. Pain and swelling are stop signs, your body’s trying to get your attention.
But certainly, that message becomes increasingly important as my patient gets older.
