I have felt really rough the last few days. Today marks a week since our booster. and the last time I have left the house. Slept like a log all day yesterday, My issue is where the hell is all this green mucus cough/runny mucus from the nose coming from? My sides hurt a bit from all the mucus coughing. Its like a lake. At least today I have managed to get up and am sitting at the computer. My pharmacist said to take paracetamol and lay low for a few more days. Cannot get though to my GP as he is hiding is his covid bunker. They just refer you to 119 and don't seem willing to help at all my GP I mean. I feel a little btter overall I guess.
I was a bit hesitant to reply earlier on because I'm not sure if my experience had anything to do with the booster or not. I'll relate it anyway.
A few weeks ago (a Wednesday) I was working in the garden until late. Making a log reindeer
Anyway, I ended up working well after dark and in the rain too. It was chilly, but due to exerting myself I was sweating. Later on, I felt grotty. On the Friday I had a Pfizer booster after previously having two AZ jabs. I still felt a bit grotty over the weekend, but by Tuesday I had a killer sore throat, had lost my voice and I was coughing up blobs of thick green/yellow stuff. Blowing my nose was like emptying my sinuses of blobs of blood and also that same green/yellow stuff. Covid tests were negative and no one around me went down with anything either. I had no aches or anything, and it wasn't like the Covid I did have in August/September. It was top of my chest to my nose that was affected.
Was it reaction to the booster or just coincidence? I have no idea. I'm only putting it out there because it sounds similar to your own experience. I just took paracetamol and stayed in bed or under a blanket on the couch. I've started going out again when I have to now, but I still cough up the odd blob of greenery, although I've improved an awful lot.
It felt different to colds I've had previously, so that can be disconcerting when a new Covid variant is about and you've also just had a vaccine jab in cold and flu season. I was 99.9% sure it wasn't Covid again in my own case, but the possibility still played with my mind.
Anyway, I hope you are feeling better again very soon. It sounds like you are over the worst of it. Take care, Scouse.
