I dreaded this happening. When I was paralyzed 8 years due to an auto-immune disorder called the Guillain-Barre Syndrome (I actually have a chronic form known as CDIP, which is easy to look up but hard to type). I recovered somewhat, but have permanent nerve damage in my legs, resulting in weakness and raging pain. The pain had been more tolerable until last year. One manifestation of nerve pain like this is difficulty with proprioception, which is the sense in our joints that indicate where our limbs are and in which direction they are pointing. This causes me to veer, list, and stumble. The really great, excellent news, which I just discovered on my own (thank you doctors for not telling me about this), is that the proprioception difficulties are tied to the amount of nerve pain. If anyone knows more about this, please let me know if I have this wrong. The upshot is that my pain is not increasing per se; it is that the medication that I take becomes less effective over time. The pain in my feet feels more and more like I am walking in socks on loose gravel. When I walk somewhere, I use a cane to take some of the pressure off my feet, but also to steady me when my proprioception affects my balance and awareness. It has gotten really bad in the last couple of months, and my wife can hear me whimpering, moaning, and emitting short, sharp yelps and grunts. I am still teaching, but cannot always part in a nearby disabled space. The trek from my car to the building seems really long, but in reality is probably nothing at all. Because of all these factors, I have started using a walker to get to the building. Once I get to my office, I switch to a cane. As many here know, I find many things in the world to be curious. Why this and not that? Here is what I have learned about using a walker on campus. When I start to head to the doors, a student behind me will rush up to open the door for me. I always say, "Hey, thanks." And they always say, "Not a problem." Of course, people use certain expressions out of habit or for the rhythm of the phrase. But from a literal standpoint, "not a problem" seems a little off. Maybe they are thrown for a loop by doing this for me, which may be something they haven't actually done before. Lest I sound like I am complaining, h*ll no. Holding doors is a huge help to someone in a walker. It is also a way to meet girls.
