For the hand splints (I know they are really expensive) the ones I have are from Zebra Splints and are a lot cheaper than most, so def check those out (especially during May, she usually has a big sale)! Hips and shoulders are totally the hardest though, I get it! For my hips, one of my biggest struggles is crossing my legs, so I would try to find solutions to keep yourself out of those kinds of positions that you know throw your joints off (like I get cold, which causes me to cross my legs, but if I warm up with a blanket and sometimes even put something between my legs, I can uncross them)
