I don't understand this. Press what? How is it done?? Sorry for being so dense - maybe it is due to languageproblems....
As if you are on the toilet, and trying to poop... or yelling,, even singing. Take a deep breath, and hold it, push the breath, without breathing out.
I do not think this is a good thing if you have CCSVI, or are at risk of stroke. The Valsalva manoeuvre basically pushes the blood back into the brain. This is why it is not uncommon for people to have strokes, blow out aneurysms, etc. while sitting on the toilet.
I have been wanting to comment on this, but my brain cannot think, or explain more than that (I have been singing to my 3 year old...).
