For the past month or more, I have been experiencing burning on my arms, legs, and lips. (Bloodwork for these symptoms has all come back normal.) I am miserable. The only thing different in my routine during the last couple of months is that I began taking Lunesta (sleeping medication) a couple of months ago. Is there ANY chance that it could be a reaction to that? If not, any other ideas? I REALLY need some help/suggestions!
