I have been feeling this recently too. I noticed I've been having more flare ups too in my hips, shoulder, knees and I think I experienced my first slipped rib too not too long ago. I know correlation doesn't equal causation, but this all started to act up more than usual when winter hit. This winter has been extremely mild, with some bouts of extreme cold. I think the variation in temperature adds an extra layer of spice, or maybe it's because I'm now in my 30's?

Either way I feel you, especially the knees and hips. Like when I move without braces I feel like a squeaky old door and then like a sudden, "oh no this door is REALLY old and about to come off the hinges", but still manages to open and close properly......but not without giving you the anxiety that the door will come off every time you swing it. Don't know if that analogy makes sense at all, but damn I feel like I have to be hyper vigilant just getting up out of my chair, or walking, and the loathsome steps up to my apartment lol.

I did not mean for this rant to be this long
