The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
From my personal experience, sounds like patellar to me. I bought the VooDoo bands just for my patellar pain. When applied right above the knee and right below the knee, they open up the patellar and let all the nastiness out.
They say a common fault to cause your patellar to inflame is allowing your knees to go inward while squatting.
