Hi all,

I felt a little like I was struggling to breathe when lying down about an HR ago (this also happens when I'm even sitting!) Really strange.

I put the oximeter on my finger it went all the way down to 92! Suffice to say I am now panicking - thinking the worst. Clot in my chest etc. I'm scared.

Interestingly when I stand then it shoots to 98 to 99.

Why is it that when I'm sitting or lying down to go to bed it drops so drastically?

It's super freaking me out. My last check up with the doc was earlier this year and all was fine.

Is this normal? Should I call the ambulance?

Need help before I end up making a fool of myself calling 999. I am hoping and praying this is normal.
