Please help me to find videos on forearm crutch use with both legs affected? Especially for walking up and down stairs.

So far I only seem to find videos for unilateral leg injury. I have chronic pain in both legs. Currently a cane user but it’s not enough, recently I tried forearm crutches for a few steps and it made so much difference.

Tl;dr: chronic pain in both legs, currently a cane user but supporting one side is not always enough, also have chronic pain in both shoulders and can’t put work on them.

I have chronic pain in both my knee areas, plus some other weird leg stuff.

I currently use a cane, alternating between which side currently hurts more. But sometimes they both hurt too strongly, and sometimes I even actually have to put more weight on the leg that currently hurts more because something else makes walking with more weight on the leg that currently hurts less harder.

I also have chronic pain in both of my shoulders. I can’t use the grater, for example, recently stopped cutting vegetables for food prep too because pain. So I’ve known for many years that if I ever need a wheelchair, I’ll need a powerchair, because I won’t be able to self-propel on the manual. Several months ago I had an acute illness that made my leg pain much worse, I was very barely able to walk, and the force I had to put on my shoulders at the side holding the cane gave me so much shoulder pain. For what this post is about I was thinking about forearm crutches, but realized they might put the load on the shoulders too.
