Interviewing and my Knee

For the past couple of weeks, unfortunately my knee's been bothering me again. It's getting the dull ache I had before surgery. I haven't tried much cardio since being in Baltimore, so we'll see. Some of the hotels where I'm staying have gyms, so hopefully I'll be able to use them this week. I have been doing my exercises, but it's still frustrating. I've also noticed my knee bothers me with lots of sitting and since I'm in the car driving a lot, that's not helping. Ugh.
