for me with the ITBL strain the knee felt like it was being stabbed... outer leg tho, not inner... and my hip joints felt sore a lot... the IT band goes from outter hip to knee...mine was overly tight and caused the excrutiating pain...

I'm no doc, so if you can, do go and find out for sure what's going on...corsair is right... you will be glad you got it diagnosed and treated before making it worse... I put it off and paid the price...
