I have been running in place for the last few weeks for about 3 days a week.  The last time I ran was last Wednesday.   Last night I woke up (I work Midnights) to go to work & when I walk up & down steps, I get a pain in my Knee & in my Left Ankle.  It doesn't feel like a muscle pain, more like a joint pain.  
My question is: Am I running wrong or wearing the wrong kind of shoes?
I will say this, it seems, when I am running in place, it feels like I am running on the tips of my toes. But, I can't seem to avoid it.
Any suggestions or ideas would be greatly appreciated!!
Thanks
