Limiting Activity -- Knees No Better

So angry right now.  My knees feel like they are a mess.  Stiff.  Tight.  I'm hobbling around like an old person.  Still doing a little reading on the Baker's Cysts and wondering if I've aggravated something in that area and may just need to take a break and rest a little.  Did 10 pushups and situps.  Trying to do those first thing in the morning.  Finding the front of my knees to be a little sensitive as well.
