Hi, There are a variety of reasons people could experience numb or tingling feet and legs and fibromyalgia are one of this and most common. Other conditions include multiple sclerosis, diabetes, tarsal tunnel syndrome, peripheral artery disease, and having too much pressure on the nerves. Treatment can be started when the right cause is found. In your case, symptoms indicate that it could be neuropathy or fibromyalgia. I would suggest doing Doppler ultrasound and EMG for a start. Till that check, your blood sugar and calcium levels since these causes may lead to numbness as well. Though occasional numbness can occur, persistent numbness and tingling can be an indication of a serious underlying medical problem. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ivan R. Rommstein, General Surgeon
