@em87 I would check to make sure you are seeing the correct doctor. My family doctor set me up with a neurologist the first appointment which took a month of waiting. I really needed to be seen by a neurosurgeon. Now after another month, I go to him next week for an arachnoid cyst. I have been having the same symptoms as you with the arm, headaches, fatigue, etc. I don't want you having to wait any longer by going to the wrong type of doctor.
