@illinilass Yes, Dorothy, I had cortisone injection and aspiration of fluid off the knee on Thursday. By Friday morning it was looking and feeling much better. But while sitting (!) at my computer around midday on Saturday my knee suddenly went out with no warning or obvious reason why.... Still can't weight bear on it. ๐ Doctors I have seen say no MRI needed and that I am not a candidate for knee surgery? But, there is SOME reason for my knee's instability. We don't know who else to consult for answers. Praying to Dr. Jesus, our Great Physician!
