I used some Palmer's cocoa butter as a lubricant , another video suggested an olive oil mix.
but with the lube or lotion on you can't really apply a lot of pressure on yourself because it's so slippery.

Someone else could apply too much pressure if they did it for you - but I think you'd tell them to stop if that happened.

I started lightly, and you also do what they call a scan , which is just going slowly and feeling for little bumps or gritty spots - that would be where you want to focus when you do the faster rubbing.

If someone has moderate to severe vascular/venous type TOS I wouldn't experiment with this technique on yourself .
