Good news, Gibb - is that a leg press you're doing? I started those at about seven weeks. I'd recommend a roller to work out the IT band tightness, it did wonders for me.
Make sure when you stretch that you've done warmup exercises beforehand. Being a wrestler, you probably know that, just emphasizing it, since the muscles are probably partly atrophied like mine were. The ROM comes back, just patience with it, you'll be surprised.
A limp is usual around this time, just make sure you've got support when you need it, don't want your body to learn to live with it.
The pain you feel, is it around the incision? I had issues with scar tissue there, worked it out with stretching and massage from the PT and later a massage therapist. You'll feel twitches for a while, and some pain from your body getting back to normal; remember that it took a while to get to where you were, it's not so bad to take less time to right it.
Take care, and congrats on no meds. Sounds like you're doing good things.
