Yesterday at about 3 PM I suddenly was struck by a wave of weakness, it began in my torso, and propagated out to my arms (mostly) and slightly to my legs. There was no pain, an no confusion or disorientation. The wave would strike ever 10-30 minutes, at varying strengths, and was ongoing from 3 until Midnight, where it seemed to subside. This morning I was feeling ok, until I sat down at work again and was struck by another set of waves. I am 30 years old, 280 pounds, 6 feet tall, caucasian male. I was on day 5 of a 20 mg Lipitor series.
