Have you had numb painful feet?

And it was not neuropathy? My sis has awful numb sensation in her middle toe now spreading to other toes. Ever have this? Also she can't put pressure on the foot because then there is searing pain. Also a squeezing pain. And the toes feel stiff..can barely bend them. One doc told her it is probably neuropathy but he wasnt sure. She is diabetic with uncontrolled sugars. But it "could" be something else. She did crack her back hard couple months ago. She will get tested soon but if anyone has had this..was it something else? If it WAS neuropathy what treatment helped?
