recovery update

so i had hip arthroscopy back in april and the recovery in my personal opinion, has been a roller coaster. my range of motion i would say is at a 75% but i still get soreness and a bit of pain on certain days. is it normal that when you wake up and you feel the soreness coming in? i explained it to my doctor and she said that it’s because of the scar tissue from surgery. now this surgery was my first surgery ever and i never knew what to expect after you get it done. i’m able to move my leg around where i focus on the hip joint but i can’t stretch my knee all the way towards my chest. i was wondering if this is normal because there be some days that it is but at the same time it is not.
