Pain in legs, any ideas?

[penguinplease]

I have got really irritating painful thighs at the moment and I have no idea why. I also have lower back pain so I guess it may be related? Does anyone have any ideas on this? I'm not sleeping properly as the pains in my thighs is waking me up.

Sounds like you might be coming down with a virus. A friend told me that low back pain can be a symtom of a virus because it is where white blood cells are made (disclaimer: I have never verified this but she is a clever biochemist).

Alternatively, are you experiencing any stress/worry right now? We hold a lot of tension in our thighs & glutes - as well as shoulders.

Lower back pain and pain down front of thighs is often associated with heavy, painful periods. Used to drive me to distraction! Something to do with ligaments being stretched I think.
Not sure if this might apply in your case though. Hope it wears off soon.
