Hello! I Am A 60 Year Old Female Diagnosed With

Hello! I am a 60 year old female diagnosed with MVP in my 20's which they said is congenital. Several days ago, I lifted a very heavy box down several steps and then into my car. Since then, I feel like I may have weakened/damaged this area. I am not having pain, just aching as if I pulled a muscle or somehow weakened this area. It is not keeping me from doing anything such as jogging and playing tennis. Will this aching pain eventually go away or could I have damaged this area? Thanks!
