After dealing with pain and tingling in my hands and forearms, I finally went to the doctor. He told me my ulnar nerve is damaged, and I have to go through eight weeks of physical therapy.
I met the therapist for the first time today. After asking tons of questions about my symptons, he said, "Do you own a Nook, Kindle or iPad? If so, do you use it often?"
Apparently, in the last year or so, my type of injury has become very common. People are using these devices, which is fine, but they aren't moving around or stretching as often as they should. Holding something with your elbows bent in a 90 degree angle for more than about ten minutes can put pressure on the nerve and also cause tendonitis.
So, I know lots of ladies on here have e-readers, and I would just like to encourage you to take frequent breaks while reading. Stretch a bit. Otherwise, you may be in for a world of pain (and a giant medical bill).
