I have been on Enbrel 4 months for Psoratic Athritis with good results. However,I have developed upper resportary infection with sinusitis along with headaches. I have had these symptons for 3 weeks. Called the Dr. today and he said to go off the enbrel for awhile. Wonder if any one else has experienced this symptons and if so, did symptons go away and did you continue with Enbrel?
