Hi Bullseye,
I'm curious, have you seen a physio about this?? what is your ITB like (tight/short), and your glut muscles (esp glut med) as far as strength and endurance - do yout fatigue around the hips when jogging or walking. Do you over pronate or supinate when you walk and does the foot position change with your running shoes on.. or do you wear orthotics?
I have found that in some people excessive ITB tension can cause a burning pain localised around the head of the fibula (the ITB inserts onto the lateral condyle of the tibia but can cause local pain at this point - google iliotibial band syndrome) and inflammation in the area could potentially irritate the peroneal nerve branch (which wraps around the neck of the fibula) which might cause the distal symptoms you get when the condition is really irritated.
i would suggest getting a good lower body biomechanics assessment to see if structures are tight and or weak (eg tight ITB, weak glutes, overactive hip flexors etc etc) and addressing that rather than just the local site of symptoms which doesn't seem to have worked long term so far.
Let us know how you go.
Cheers
