For those who have had an MCL injury, what did you do to help with recovery to get back out there mid season?

I’m open to advice, obviously rest, ice, compression, elevation. I’m onto the second week of recovery. Pain has subsided, leg still doesn’t want to fully straighten out. Gets a little stiff. Feels better when I start to move around and loosen it up, but not overdoing it. any specific exercises, stretches, etc? Yes, I went to a doctor and was diagnosed with a grade 2 MCL injury in the right knee. Very mild Grade 1 MCL sprain in the left.
