Post Orthostatic Tachycardia Syndrome.
It's from autonomic nervous system dysfunction (due to lyme and co's.)
When you rise from sitting your pulse will increase 30 bpm or more.
Sometimes it affects blood pressure as well.
You can have veinous pooling in the feet.
It sounds like you could have it OriolCarol.
What's the 'sale' position?
So next time you get up from sitting - do a quick pulse check...and see what it is.
