You're about to get tl:dr stuff, or at least TMI. The episodes consist of intermittent spasms. Each one usually lasts 1-2 seconds, which doesn't sound like much. However, the pattern is usually spasm - 30 seconds to 1.5 minutes without the spasm - followed by another spasm. This continues for hours, days, and in this case, two months. Most of the spasms are, as I've sometimes described, like labor pains in my back. Another type of pain connected to the spasms is a knifelike pain that sits on the border of my back and my upper side. It is more constant, and it's the pain that often keeps me up at night.

It's all fun.
