I'm feeling a bit anxious about my oxygen levels. After having COVID, I've noticed they fluctuate quite a bit. For example, when I check with a pulse oximeter, it sometimes shows 92 on one finger and 97 on another. What could be causing such a difference? Is this something I should be worried about, or is it normal for oxygen levels to act like this after recovering from COVID?
