I have been having a relapse, and as well as feeling like I have the flu ( which I haven't) and headaches, and all the usual cfs symptoms, my old friend the vertigo has returned. It is especially bad in the night when I turn over and the entire rooms spins for a few seconds. I am also really stuffy with sinus and ear fullness again which I always get in relapses. IBS nightmares,palpitations and so on have come back to haunt me. Does anyone else have vertigo in relapses which seems to be worse in the night?
