Getting Severe Numbness In Foot. What Is Causing This And Cure?
Numbness that is jumping between sites in a leg or arm is indicative of some sort of Neuropathy.
It can be mononeuritis multiplex.
If you are a diabetic then there is a possibility of Peripheral neuropathy.
Sometimes Sciatic nerve root compression can cause numbness in leg & foot.
And rarely a serious disease like Multiple sclerosis can have a manifestation like yours.
So yours is a very complicated case and you need be examined in person by an experienced neurologist.
You would need extensive physical examination, brain and spine MRI, Thyroid profile, Vit.B12 levels.
But first get the fasting blood sugar levels so that the status of diabetes can be checked and if found uncontroled hyperglycemia then no further investigation would be required.
I hope the advise would be useful for you.
