So I had my fifth shot of Enbrel on Tuesday, woke up this morning dizzy (can't drive, feel unstable on the feet etc.). I have had problems with benign positional vertigo in the past (before AS and Enbrel), and this feels just like that. My sinuses feel full. Anyone have this experience? I know sinus issues are an Enbrel side effect, so maybe my sinuses are flaring and throwing my equilibrium off. I am seeing an ENT on Monday as my rheumy says that is the likely cause. Other experiences would be helpful. I am hoping that this does not mean that I will need to stop the Enbrel. Thanks!!
