I think it'd be a good idea to get a thermometer so you can keep track of your symptoms. It's an important gadget to have in your first aid kit, once you go on meds like Humira.
I'm not sure what time zone you're in, but if I were experiencing those symptoms, I'd be ringing my doctor (gastro specialist) first thing, and maybe the dermatologist too. And remember, if in doubt, go to hospital: better safe than sorry.
