Hi JayGee,
Looks like I have the same issue as you had - subluxation of the proximal fibular head. I am dealing with it for 5 years already. I read your post a while ago and started to do hamstring strengthening exercises and stretching my peroneal nerve… Did you ever get rid of this problem. My fibula is still loose and moving, clicking and snapping. It is problematic, nothing seems to really help. Did you ever heard of prolotherapy … I heard it could help but don’t know much about it.
