Hedgep, so glad you decided to join the forum. Welcome!!!
As Jo said, remember that you are still VERY early in the recovery process. I had various pains on the side of my knee for at least 6 months. In fact, I even went to my surgeon at about the 6 month mark because of a side pain (mine was mostly on the inside) and was told it was soft tissue swelling....take anti-inflammants, ice, and don't over use the knees for a while. You know what? The doc was absolutely RIGHT!!! I did as he said and the pain went away. It still comes around now and then (lesser though) at a year out from surgery if I over do it. So don't be surprised if that happens to you down the road.
I hope you are still on a regular scedule of pain meds. That should really help you a lot. I stayed on my prescription meds for almost 3 months, so don't feel like you need to get off them if you still hurt! You need good pain management to be able to accomplish the PT goals that should be part of your recovery process.
