What is it?: My co-worker had to see the Oncologist & Hematologist after having many tests (looking down makes his body numb). I'm scared for him, what does have? ANS: I am worried about him also. But even if I knew what he had I could not tell you unless he gave me permission. I would ask your co-worker what he has or ask him to give you permission to talk to his Dr. If he wants to share he will.
