Pain Interpretation

I've always been pretty good at interpretting the physical ailments of myself and those close to me almost as well as I have been able to interpret dreams. I have a little knack for it. However, this one is throwing me for a loop.

Since I had my son I have had a pain in my left leg. Just a little pain. I never even though to mention it utnil this week. Well, sometimes I'd think to mention it, but I never did. There was just too much other stuff going on. It wasn't a big deal.

It's been growing incrasingly worse slowly but surely. Today it is really bad. It's in my upper thigh and I can't put any weight on it wihtout it being very painful. Today even my right arm and back hurt badly too. It's a muscle thing for sure. Muscles help me move, allow me to be flexible,I get that. But I think right now I am more flexible than I have been in years. I am wondeirng if anyone has any insight on this? Or is getting any as they read this?
I don;t know what chakra this would connect to...
