I have had psorisis in my scalp, accompanied by moderate to severe arthritis for eight years. I began taking Enbrel six months ago, but it seemed to "fail" in July of this year, 2011. I was approved to receive Stelara. It has been two weeks since the initial injection. My scalp is itching badly, my joints are all engaged in arthritic pain possibly more severe than what I endured for eight years. My healthcare provider suggests I "ride it out"; we'll check on everything again in two weeks. Opinions? Quite scary, actually. Thanks.
