I've just started Stelara a few months ago and it was working great. I had the initial starter dose and another dose 4 weeks later. I was almost completely cleared. Then as the time approached for my next injection I started to flare up again. It's been ten days since the injection and I am still flaring up. Has anyone experienced this? It's hard to just wait and see if it goes away again. I'm wondering if this is a normal reaction or if this means I am no longer responding to the medication.
