Yeah, best to take it easy for a while. I'll second what Carbonfiberboy said about taking a few days break now, from everything. I made the mistake of trying to rehab my knees immediately. I started doing muscle building exercises daily without giving the legs the time to heal. Don't think that helped at all.
I've just seen my physio today, she's told me to stop all strength exercises for a month and just focus on flexibility. Mine's very poor for a 21 year old. Also, the bodies like a chain, one part affects another. My knee problems could stem from a tight back or tight glutes, for example, so I've got to work on everything now. It's kind of a pain, she said I'll have to put in loads of time if I want to see improvements. Fortunately I've not got much on my plate at the moment.. got lots of time off work over the next month or two so I'm really gonna hit it and hope it's worth it.
Let us know how you get on with your rehab.
