I had Omicron earlier this year. Currently dealing with a head cold. All in all, I'd rather have the omicron again. I got a lingering cough from that, but never did have a stuffed up sinus problem. I hate stuffed up sinuses. I did have long-term smell/taste issues, but those have long since cleared. But omicron was less impactful than the flu or this cold.
i got omicron too- it was kinda rough, but not as bad as soem flues I’ve had in the past- had a couple of respiratory ones that really knocked the stuffings out of me- ended up in hospital with difficulties breathing- they put me on a machine pumping meds into lungs- and after awhile i was breathing better- then another i coughed so hard i had something pop around my rib area- felt liek a broken rib, but i think i just strained something coughing so hard- that was a whopper of a flue too-
