Slacking

So I haven't exercised in almost a month and my body is feeling it now.

When I walk up the stairs it feels like I am carrying my son as well (he's almost 50 lbs). Is that even normal?

I'm so mad at this knee ish. And the nerve of my insurance company to deny my MRI. Now I have to go see the orthopedic surgeon to over ride that decision, well if he says that I need it. But DAMN IT I DO!

I'm aggravated beyond belief. My body feels like it was beaten up and that is not a good feeling at all.

So what should I do?

Should I go back to moderate exercise, taking it easy? Like walking? I can't take this at all. Just a rant especially since the scale isn't being nice.
