Hi there
Pain travelling from the styloid process, dorsally over the cuboid, towards the lateral malleolus...
My DDx:
- cuboid stress fracture
- sinus tarsi syndrome
- subtalar joint pathology
- calcaneo-cuboid joint pathology
- 4/5th MT-cuboid joint pathology
- sural nerve entrapment
- peroneus brevis tendon pathology
, of course there could be many more weird and wonderful things.
You should attempt to try and specifically locate any point of reproducible pain, and that will help narrow the possibilities. Is it worst along a joint line, a tendon, a specific bone. Get weight-bearing x-rays and assess the lateral column for any faulting or DJD.
Consider the nature, location, aggrevating factors, etc to help distinguish between nerve pain, and joint pain for instance. Get back to basics in your assessment and history to try and figure out which tissues are being affected. Hone in on your surface anatomy.
It sounds like the previous therapy was rather 'humble', so trail some functional taping to check the effectiveness of better stability through the hindfoot and midfoot.
Let me know how you go,
LL
