@jimiwho I am certainly not a doctor so this advice is just "wonder if" If you are considering using Oxygen, the question has to be if you need it. Ask the NP or doctor if it would be worthwhile to get one of those finger clip things that measures your oxygen levels and see if when those things occur if your levels are low. That might indicate if you need O2 or not. I hope you can find some relief somewhere. Oxygen can get bothersome and expensive.
