Head of the Fibula

For the past few month I have been getting pain in the head of left fibula. It seems to be lifting off its origin on the tibia. It doesn't prevent me from doing anything, its just annoying. I previously injuried my left side with damage to the illio tibial band. I have spoken to two physios and an orthopedist- none know what it is. After 3 weeks of nothing but walking (no weights, no running, no mma, no yoga, etc.) it has not gone away. Any ideas? If this seems like it will become a chronic low level injury and I do not want it to eventually break my fibula.
