Knee x ray

[Lumobile]

I'm going for an xray on my knee next week.
Can anyone tell me what to expect? I know that an x ray isn't painful but I get the serious jitters around anything medical.
Do I have to undress/put on a hospital gown? I think it's those gowns with the flapping rear nudity that I'm dreading the most!

Wear a skirt or very loose legged trousers that you can roll up.
It will take about 5 minutes or less.
You may have one x-ray standing up and a sideways picture lying down, or both standing or both lying down.
Please don't worry about it, it really is a very simple quick procedure.

Thanks for the reassurance Bearcat
I've got some stretchy wide legged trousers that I can roll right up, so I'll wear those.
