I had a terrible heart reaction during an infusion with Remicade and I also had anemia (blood disorder) from Remicade and Methotrexate. Every med has a side effect, some side effects are just worse than others. Sometimes if you remove the offending med, the symptom goes away, so hopefully your psoriasis will go away.
Have you tried taking out the starches in your diet? I felt so much better when I took out starches , dairy and nightshades. Hope you feel better, take care.
