Hello everyone. You all had been quite helpful in responding to my query. I appreciate that. Just to fill you in, I did start going to the physiotherapist and that has helped me quite a bit.
I am hoping to get some input on a more recent development:
I have developed severe pain a little above my knee for the past 1 week.
I got an x-ray done and everything related to the fracture/rod seems fine.

The pain is very severe when I'm climbing stairs (in fact I can't climb them - I go up one step at a time) and getting up or sitting down. While walking/standing I don't have any. It is only when my knee bends to the point of going in front of the toes that this sharp pain occurs.
I was wondering if any one has any thoughts about why this may occur. There doesn't seem to be any trigger to this. I've been dong light gym/physio work quite regularly for a couple of months.
Also, the pain seems like it is muscular/nerve related than bone related directly.
Doc says - 'take it easy it'll go away', but I'm quite concerned.

Thanks.
