Where exactly is the pain located? Can you mark a googled pic where it is?
Also, any other movements confer similar pain or twinges?
Like I said in the other thread:
PNF stretching + heat + self massage + foam rolling
MAY be a strain.. in which case:
But the other thing that may be a problem is a tight popliteus or other muscles up high on the knee. The vastus lateralis may be a problem that is manifesting lower too... depends a lot.
