Confused

Oooh Sammikins....what bad news I wish I could help, something is going wrong of that there is no doubt, but what it is is difficult to pinpoint, sometimes it's  just a change of environment that makes the psoriasis flare up, not sure why you should develop mouth ulcers and possibly a fungal coating like thrush on your tongue.
I would be inclined as soon as you get home to contact your hospital and tell them, in the hope they can change your medication as it may be a reaction to either Humira or methotrexate
