Are you feeling weird knee pain ?
Have you tried foam rolling but still Unexplained?
This may be of interest to you. The Voodoo floss around the lower lateral quad seems to help me alot.
It traps all the tissues that act on the knee joint at the same time in the range of motion you feel the issue in.
Hamstrings , adductors and quads all get work together .
Here is a video on a technique I used to fix my weird knee pain , I hope it can help you as well.
