I had three infusions then it was stopped as they thought I'd gone into remission. Three months after the last one, I developed pretty severe psoriasis lesions on my feet and lower legs.
The thing is, I think I'd started to have small patches before I first got abdominal symptoms, but when they put me on Prednisolone they cleared up. I was tapering off the Pred when I started on the Remicade/Infliximab.
My GP - who's a skin specialist - emailed my GI and he replied that they had had several cases where people had had incidences of psoriasis flares, mainly on the feet and ankles, while on Infliximab and advised the usual treatment i.e. with Betnovate ( steroid ) ointment which did help clear it up for me.
That was January last year, but strangely enough, it's started flaring up in the same places again, although not as badly as it did while I was on the Remi.
