Please check first
If one arm and leg suddenly become numb and weak, if speech becomes slurred, or if the face turns to one side, emergency care is needed right away.
Numbness in the hands and feet can be a sign of another condition such as diabetes, thyroid disease, or vitamin B12 deficiency, so confirming the cause comes first.
If numbness lasts a long time or gradually worsens, it is better to be examined at an internal medicine clinic or similar.
