Totally agreed. I woke up once with severe arthralgia throughout my entire body, went to the ER and was asked to rate my pain level. Despite being the worst pain I've ever felt (woke up in tears due to the weight of the blanket on my toes), I answered a 7/10. Acute pain – not really a big deal.

Unfortunately, whatever caused the arthralgia was (and still is) a complete mystery, and by day 5 of having top pediatricians explaining "nothing is out of the ordinary" I pragmatically, unemotionally contemplated suicide for the first time in my life. Somehow the ailment completely disappeared over the following weeks and hasn't returned, but it's quite something to feel that pain will truly and honestly never stop. It's not even that your brain goes into panic mode. It's a different mode of existence altogether – I can't even imagine people suffering through years of pain even 1/100th of the intensity of what I had.
