Sounds unusual. It sounds like a sensory branch as I assume you don't have any weakness (flopping foot when walking).
Did it happen suddenly or more gradual? Did it happen when you tore your MCL? I have seen symptoms like this with some sort of compression injury but to not have muscle weakness is more unusual. The nerve that hooks around the fibula is a large mixed nerve containing both sensory and motor nerves.
If it is a neuropraxia (a bruised nerve) it will take some time for the nerves to settle. The tingling will be annoying and just be careful when walking over uneven ground as the altered sensation will affect your balance.
A dislocation is possible, though I've never encountered that before, and they could probably track the nerves path and movement with ultrasound scanning.
Sorry I can't be of more help.
Monty Python's version of the cougar phenomenon:
"This is a frightened city. Over these houses, over these streets hangs a pall of fear. Fear of a new kind of violence which is terrorizing the city. Yes, gangs of old ladies attacking defenseless, fit young men".
