[|Human|] Have developed pain in left foot, especially when walking. Seemed to start underneath, as in plantar fascitis, but now more under ball of foot and top. No injury. I do take a Symbicort inhaler which physician indicated could result in foot numbness, but this is pain.
[|AI|]  Hi, There are a variety of reasons people could experience numb or tingling feet and legs and fibromyalgia is one of this and most common. Other conditions include multiple sclerosis, diabetes, tarsal tunnel syn Chat Doctor.  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
