Stelara is not working at all for me

I have been taking it for a year and a half and quite disappointed to find out it has not been working this whole time. According to regular blood tests, CRP levels are normal, but colonoscopies always showed evidence of really bad inflammation. I always knew i had inflammation despite normal CRP levels as I had pain.

I feel like giving up. My doctor chose Stelara over other drugs as he said it’s the most “advanced”. If this isn’t working for me then what will. Has anyone tried not responded well to Stelara but responded well to Humira or other biologics?
