hi..Numbness is most often caused by damage, irritation or compression of nerves. A single nerve branch, or several nerves,Certain diseases, such as diabetes, which can damage the longest, most sensitive nerve fibers (such as those going to your feet), can also cause numbness. I would advise that you get your sugar levels, thyroid and ur vitamins checked and consult a physician who after reviewing the reports well advise u on the best course of treatment

Need to be evaluated personally by the neurology expert Need further questions... Biochemical test and mri scan if needed
