Anyway... enough about them. The main thing I am looking for a frequent wear splint/support/etc. for is a knee. I have small problems with them hyperextending, but that gets miles worse when I have over-walked on it and they go back miles, left side in particular. Most frequently they wiggle within the joint (actually, they do that all the time, but it hurts more in some situations), mostly side to side, so a hyper-extension stop type of hard brace won't help that, but it's what one physio said I needed to stop the knee falling backwards by mistake and crashing me to the floor. So then they said put a Tubigrip on it (which is latex, I am allergic, whole other thread!) so I am wondering if there is any combination of lycra support with hard brace on top type of thing. I'm confused!! I am not after a recommendation, as I am going down south to a medical supplies shop that will do recommendations, but I don't want to go having no clue what they are showing me as I am at their mercy for an expensive sale then.
What do you have, and what does it actually do?
