For me I know I need fluids or to go to the ER when my chronic pain becomes unmanageable. I have different ways of managing it at home but if it gets to a point of no return and I have to get back to class I go to the er and get a migraine cocktail of sorts. I normally feel better within a few hours. I try not to do it too much because a lot of the meds you can take at home but fluids are sometimes the best option.
