Two days ago I started having numbness in the 4th and 5th fingers on my left hand.
I tend to ignore medical things until they really begin to irritate me, but everyone had such an immediate response when I mentioned the numbness I decided to call the doctor.
It just so happened that one of the questions that the nurse practitioner asked me was about headaches (she also asked about chest pains - no chest pains at all) and I had to say that yes, I have had some dizzy headaches lately. I attributed them to running out of allergy medicine a while back and going without for several days (turns out I was correct on this). Anyway the nurse had a fairly strong reaction to the admission of headaches, especially dizzy headaches, and asked me to come in (they really should not put such excitable people in a position to counsel patients).
So I took the afternoon off, drove to La Crosse and waited for a squeezed-in visit with the doctor. It took him a whole 3 minutes to decide that I was not in any danger of a heart attack or a stroke and that what I had was a compressed ulnar nerve - a condition which normally clears up on its own, but sometimes requires surgery by an orthopedist who specializes in hands and elbows to move the nerve to a new location. Usually they only do this if a person starts having muscle wasting.
Today I am working with a neoprene pad under my left elbow and trying to keep it unbent. It is going to take some getting used to. I need to talk to HR about an ergonomic study of my workstation.
