I'm sorry you are experiencing all of this. Numbness is really hard to treat without knowing the cause, which there could be a number of things causing your numbness. Maybe discussing treatment options with your PCP might be a good idea. He may be able to at least prescribe something to help with the numbness (such as gabapentin or Lyrica) to see if that helps you so you can return to work. The numbness could be from diabetes as well. Contacting your endocrinologist may be a good ideas too and see if they have any ideas or suggestions.

I hope that you get an answer from the doctors at John Hopkins soon. Let us know how you are doing!
