It could be circulatory but it could also be nerve related. Pressure on a nerve anywhere from the ankle up to the spine could cause tingling. Is she having color changes in the foot (blue or red for example)? Usually if there's a blockage or spasm (like Raynauds) in a blood vessel, you'll see color changes. Is she diabetic? If it's very painful or causing her to stumble, she should see her doctor soon.
