Tracy, I think you need to start a new post because you need help!!!
The afternoon before my crisis, my O2 saturation would not go above 93%, no matter how much I rested. That's a huge warning sign for two reasons. One, it wasn't my normal, as Alice alluded to. Two, it wouldn't move/fluctuate.
And your O2 was 93% while sitting. What was it if they had walked around with you, which they SHOULD have done. They also should've done an arterial blood gas, so ask for that next time.
From everything you're saying, you aren't well. No more activities!!! I understand that church is important but so is being alive. Sitting up is very hard work for the chest wall muscles that help you to breathe.
If you have sudden shortness of breath, that's another huge warning sign. The inability to move limbs well is yet another reason to dial 911.
If you don't take care of this right now, you may end up on a vent.
