from taking tramadol ( i also take lyrica) I take these for fibromyalgia. I only occasionally get these symptoms. My body twitches in different areas, it could be my shoulder one minute, my hand or foot the next, even my mouth. At these times my tongue seems to trip over itself, so to speak, I'll be talking just fine and all of a sudden I have trouble saying something, it's almost like my mouth is trying to say something faster than my tongue is able to get the word out. it's really strange, and kind of hard to explain. I was wondering if anyone out there experiences this or something similar?
