Symptoms first presented when the key for my bike lock broke as I was opening it. No problem, I thought; I have a spare key, and since I did, it was no problem. Then today, the lock wouldn’t open. Strange. Could these symptoms be connected? But how could they? How could a broken key — cheap plastic casing couldn’t take the torque when I turned it and the key split in half — break the lock when I used a totally different key later? I was stumped. Then, after popping a vicodin, it came to me: what if my initial assumption was wrong? What if the lock was already becoming difficult to turn, and the broken key wasn’t the cause but a symptom of that pre-existing condition? The additional pressure necessary to get the key to turn could have been just enough extra stress to break the key.
However, it is also true that these symptoms could have been caused by lupus.
