Steroid timeline

Hello everyone. I’ve been on this injectable steroid called Skyrizi for my plaque psoriasis for about 5 days now. My doctor told me it was a fast working injection and I have yet to see any results. I was wondering if anyone out there experienced any injectable steroid like Skyrizi and if so, how long did it take to see results? I was excited to get on it but nervous it might not work now. Me being covered in p I really want to find some answers. Thank you!
