Hi Dr Ashori here, please give me a moment to reply.
Were you given a diagnosis of diabetes in the past? Do you have any other medical conditions? Also, what medications do you use?
Numbness in only those digits means that it's likely not from blood sugar, hormone problems or any circulation.
It's usually a pinched nerve in the ankle or near foot somewhere.
There are things like Tarsal Tunnel syndrome which can pinch nerves in the foot.
I would suspect the nerve is getting pinched somewhere near the foot or ankle and causing the pain that you are experiencing.
To treat it you would need xrays by someone who specializes in the feet/ankle and then determine based on the exam if you need surgery.
If you don't want surgery you could take medications for this but it's often a medicine that makes you a little sleepy, you could take it at night and that's okay because it will last in your system for 24 hours.
I can recommend some medications that you can discuss with your doctor.
Is there a lot of pain or weakness or does it bother you because it feels abnormal?
