I have also just recovered from Omicron..
It's weird to be informed that you are positive, and a bit disconcerting at the same time... purely because you don't know what to expect it to do to you.
My experience was this:
It hit me quite hard in the sense that I was constantly tired.... I literally just wanted to sleep.....
Bad lower back ache.... which I had originally attributed to some weighted squats that I had done in the gym within the previous 48 hours.
Slightly scratchy throat, nothing serious at all.... in fact hardly anything at all, but something was there
Headaches, throbbing at times.....which I never ever get, and that is actually the reason why I went to get tested, because then I knew something was wrong.
Laboured breathing, only because it just completely blocks up your nasal passages and it is just very unpleasant to think that you can't breath properly, and you are sometimes forced to breath through your mouth only...... not cool.
Moonrover is correct, mine lasted for about 5 days, but I isolated for 8 days
To summarize, it is not nice, and some friends I know who also got Omicron have had different reactions.... one friend, who is doubled jabbed... nearly ended up in hospital, but he has irregular heartbeat issues .... and another person who is totally against the vaccine, and refused it, really got hit very hard by Omicron, which is the lightest version of any Covid so far.... but they all got through it ok.
I am glad I am over it, and that I got through it without any issues..... and the fact that I also now have some natural immunity against Covid, can only be a good thing I guess
Do what you can to avoid it, one never knows how it will affect you, compared to others....
