Could you call your GI or whoever prescribes your Humira? That would probably be a better place to start since you do not feel like you are in a life threatening situation. The ER will not be as familiar with Humira side effects as your prescribing doctor would be, I would presume. Get calling before they close and if they are closed ask if the on call can call you.
