My dad is having extreme pain just above his knee and is unable to sit or lie down for more than 10 minutes before the pain is excruciating. He doesn't complain until it's really bad. His surgery was Tuesday morning and the doctor felt that it went well, a lot of arthritis and bone spurs. Dad has been trying his hardest at his PT but noticed a very bad pain just above his knee. He's still unable to lift his leg without ***istance. Movement seems to be okay. The folks at PT thought it was probably his stitches hurting. He had an xray done this morning that didn't show anything. Mom asked me to surf the web in hopes of finding someone who has been through this. He was supposed to be discharged today but instead is just discouraged. And he still has to do his other knee eventually!
