Don’t assume that MS is always the cause of numb or tingling feet. While multiple sclerosis is a common cause, other conditions can affect the feet, too.
Numbness of the face, body, or extremities (arms and legs) is one of the most common symptoms of multiple scelerosis (MS), and can occur very early in the course of the disease, according to the National Multiple Sclerosis Society.
But numb or tingling feet can be caused by a number of conditions other than MS, some of which can be treated or reversed. This means that while MS might be behind what’s happening in your feet, you shouldn’t assume this is the case. And sometimes, numb feet can be a sign of an undiagnosed condition — like diabetes or a nutrient deficiency — that requires urgent treatment.
Here are some of the most common causes of numb or tingling feet, along with some of the signs that may point toward one condition or another. It’s important to note that only a doctor can determine what’s causing your foot symptoms, and you should report any changes in sensation in your feet (or anywhere else in your body) to your neurologist or primary care doctor.
