I have the most peculiar symptom, and wonder if anyone else has experienced anything similar. In 2010, I took Lyrica for a short period of time. Upon discontinuing it (my MD felt no need for me to taper from my "low dose") I experienced twitching muscles, anxiety, and burning facial pain. After a few years, the facial pain was entirely gone. This evening, I have been using my brain in a vigorous way that I'm not accustomed to doing. I'm trying to relearn some chemistry from high school. This involves quite a bit of focused mental activity. This is causing my face to burn quite a bit. The pain is bearable, it's just a sad reminder that I have neurological problems, though.
