3 middle toes are numb all the time on one foot. lot of pain in ball of foot when walking. toes also go red and burn when very painful. mri normal?

Circulation problem: From your description of the color changes, it sounds like a circulation problem. (MPN nerve problem should also affect the big toe). The MRI is useless in this situation, unless an MRA (MRI Angiogram) is performed in a special high-field MRI machine. Your best bet is to talk to a podiatrist & discuss your ENTIRE medical history, including any smoking history, varicose veins, family problems, &c.
