Sudden left knee pain

[steph410]

I just got woken up by sudden pain in my left knee. I workout 4 times a week and use the elliptical 2 times a week. I stretch before every session. I'm 36 years old. Could this pain / injury? been cause by some power lunges I do or just simply some squats. It doesn't hurt to the touch, but there is some pain.

Hi,

I need a bit more information.
What kind of pain is it?
Where around the knee joint is the pain?
Have you got history of any other leg injuries?
Was the waking in the night the first incidence of pain?
What triggers the pain now?
