Hi. I am not an expert in this matter but follow this home remedy.
Problem: Your lower limb is getting slow blood circulation. Uncontrolled high blood sugar levels in people with poorly controlled diabetes can cause peripheral neuropathy, or numbness and loss of sensation due to nerve damage.
Solution: The massage of almond oil can increase the blood circulation in your lower limb. Do not walk barefooted, even around the house.
Again, you should get an expert opinion.
