Hypermobility and Spontaneous Limb Collapse

I think mine might be muscle weakness related but I experience something similar. (I’m getting a rheum consult about it soon) Like when I go from sitting to standing or am walking sometimes my legs can “give out” on me.

every day my knees and elbows come up with new ways to betray me. fell over and tried to get in my wheelchair? my elbows give out and I slam my nose into the kitchen floor. tried to stand up like a normal person? nope, knees aren't in the right spot and they put me right back in my chair. oh, I was gonna get back in bed? what if every joint in my load-bearing arm gave out all at once? good luck getting back in bed when you can't move 😈 it's a constant battle to stay mostly upright

What do you mean collapse? I know sometimes my legs can't hold me because of the pain. But I'm not sure what you mean by collapse
