More than likely you have a dorsiflexion limitation at the ankle joint.
(the varus wedge helping also makes me think that, along with the current symptom)
This is the same joint limitation that is also often responsible for plantar fasciitis, sometimes involved in knee issues and over-pronation and externally rotated feet.
It's a common human condition.
If you've got a PT handy, ask them to check your range and to teach you how to mobilize your own ankle into dorsiflexion. (it looks vaguely like a standing calf stretch, but is completely different) You do that 10 times every 2 hours until the symptoms have been gone for a full week.
If you don't have one handy, I can try to describe it. But I can't diagnose over the internet, you are best off with a real-live face-to-face PT.
