How To Cure Pain In Right Femoral Head Post Pinning Surgery?

I have some concerns regarding recent pain in my right femoral head. I had a stress fracture repaired 4 years ago via femoral pinning surgery, and now have 3 titanium screws running through it horizontally in a triangle pattern.Recently I have been experiencing a good deal of pain and tenderness that feels just as it did when it was broken originally. I have not changed my exercise routine in any significant way, and am wondering if our recent temperature fluctuations here in Colorado could be to blame.I have experienced weather related tenderness before, but never to this extent. However, this is also my first winter in Colorado (I was previously in North Carolina) so I am hoping this fluctuation is to blame.Is that a feasible reason, or should I be concerned?
