I've had a lot of side effects with lamictal but that doesn't sound like any of them, so I *think* you might be safe crossing that one off the list. It's not generally considered one that causes many issues. That said, I did have some muscle aches and general not-feeling well at the beginning (so tired), but the location of the muscle aching wasn't quite as specific as you are saying for me. (Dont you hate how hard it is to figure this out when they all get added in at once? I'm going through this right now too - my p-doc added in four at once to try to stabilize me and I'm having a heck of a time trying to figure out what is causing what!)
