Hypothyroidism, diabetes, tumors and infections of the ulnar
and spinal nerves
and rheumatism
can all cause numbness of little
and ring finger. Please consult a neurologist with your MRI and EMG reports. You will probably need extensive physiotherapy, and may need to take non-steroidal anti-inflammatory such as Aleve or Mobic. Hope this helps. Take care!
