Hi. Most likely this is a nerve pinch either at the ankle level, or, much less likely, in your lower back from a disk problem there.
Diabetic peripheral neuropathy is also a possibility but usually that affects the entire foot
You need to see a doctor for an exam, blood work, and possibly an MRI of either the ankle or your lumbar spine
Let me know if you need any more information please
