You said, "My oxygen was 87 the first day I got here, today it’s 93……." That's great news! That means your body is acclimating to the altitude. Travel at altitude is scary for me because I can never get my O2 above the mid-80's.
Today we had an air quality alert, and I was outdoors tending to guests - I bet my oxygen was below 93 all day - at 900 feet of altitude.

So I have read more about your tests, and don't see anything alarming.

Also, when you feel anxious or in pain, can you try 4-4-4 breathing to calm yourself? Sit or lie quietly, put your hand on your belly and breathe in through your nose for a count of 4, hold for a count of 4 (if you can) then breathe out through pursed lips for a count of 4. You should feel your belly expand and contract as you do this. As you do this visualize your worry, fear or pain blowing away on your outgoing breath. Repeat at least 5 times, or as long as you need to until you feel calm.

This is a technique I use to calm pain spasms, shortness of breath, angry thoughts... Can you try it tonight to fall asleep without worrying?
