Thank you for sharing Lamees!
Obviously, the constant pressure to run and fight was "too much" for your knee, and the sidedness may give us another hint as to where to look for what theme can still get you aroused. Pain being on-off in a chronic process means you can and do resolve, but don't reach sustainable balance and resilience.
If you breathe inside the knee with the intention to encourage it to share what it needs to let go of the pain signal and for you to heal completely, what message do you get?
