Does anything get any better with Otezla?

I've been on Otezla for about a year now and while there's a little improvement in the psoriasis in my ears, it hasn't done much for the patches on my scalp, it hasn't stopped it from developing on my privates and it makes me so tired and nauseous. Does the nausea ever go away?? My dermatologist really made it seem like if I moved to a biologic I'd get Crohn's and blood cancer so I guess I'd rather not switch but I'm so tired of being sick and tired. Does it ever get better?? 😭
