My physio is certain I have it and after reading up about it I'm a text book case.
Had an ankle injury a few years ago followed by surgery in March. Pain in my ankle has been chronic for years but dramatically worse since the surgery.
I can't bare anything touching it. Scream if the duvet rests on it at the wrong angle, can't sit cross legged as I can't stand the outside of the ankle touching the floor, can't wear ankle boots, can't touch my ankle with my fingers unless I have a sock over my hand. Non stop burning, throbbing sensation in my lower leg, worse in my ankle.
Google gives some depressing results with talk of years of worsening pain.
