Hi all, I am having a really really bad flare up of my FMS & CFS. At least i think it's that. I am dizzy, tired, nauseaus and feel very weak. My lungs feel constricted and short of breath (costocondritis) I've been feeling this way for 2 weeks. It's so bad I'm getting afriad. Anyone else get these symptoms and what do you do for them? Also, how do we know when it's our DD and not something else?
