I’m not a doctor either, but I’ll add my personal experience to the discussion, in that I had omicron over the holidays which was miserable. I’m vaccinated with the one shot jnj, not boosted. Despite most of my friends having an easy time with omicron, I did not. After about four days of being bed ridden, a cough slowly crept in and which has not gone away since. I have gone to urgent care and done a z-pack cycle for it, as well as a steroid inhaler. It’s slowly getting better, but my coughing fits we’re so bad at times I was wishing I had a little oxygen canister to take some breaths on at times, because the marginal amount of air I was able to breathe in during these fits made me feel very low on o2. Once the fits would subside again I would be fine. But having a can to breathe on would have been very comforting, if only mentally.
