patellofemoral pain syndrome

Now...I was having knee pain in both knees, sometimes it would feel like they would lock up.
I was due to see my primary so....waited until I seen her....
So I went to go see her and she didn't like my cholesterol level so she put me on a med for that, then put me on a muscle relaxer , sometimes I feel the need to get up and move( restless leg syndrome)...then informed me I had arthritis in my both knees, she ordered a x-ray for both knees, referred me to an orthopedic doctor.

So went to the orthopedic doctor and he gave me a cortisone shot in both knees...
for the most  part they have helped, except the last few weeks, my left knee has been hurting.

Then out of the blew....a physical therapist called about scheduling me therapy session....Ok, I didn't know anything about the therapy....

I contacted the orthopedic doctor about the pain in the left knee and he is sending for a MRI  sometimes, just waiting for the call to get  the MRI....

I had my first PT today...my left knee hurts.....told me that I need to strengthen my thigh muscles to help with the knee pain.....to me that don't sound right....anywho...that's it for now
