So I had the Pfizer booster yesterday and everything was fine until the evening. I started to feel cold so added a blanket to my bed. Woken up today and feel like I have been hit by a bus. I am so busy at work (WFH) and have lots of deadlines so can't afford to take time off (no-one else to cover my work and am going to have to work the weekend to catch up on todays work that I couldn't concentrate on). I am a terrible sick person and feel so sorry for myself so I know I am being an ass. I just wondered if anyone else had the same issue and when did they feel better. Lying I'm bed with 2 duvets a jumper and cardigan on and still feel so cold and feverish. I have taken an LFT which was negative so assuming its the booster. Wish I hadn't bothered now. (See I am a pathetic sick person). 😫 can anyone give me any hope? Thanks
