Same day. Got the shot at 2:20pm, symptoms started about 9pm and got continually worse throughout the night

I got the second dose of Moderna earlier today. I will not lie. I am flat out knocked on my ass miserable. The first dose wasnt too bad. I had a very very sore arm but only for about 2 days and some fatigue. That was it. This time is the total opposite. Fever of 99.5 (i normally run bwlow 98), chills so bad my body is convulsing, dizziness, nausea, restlessness, and PAIN. OMG the PAIN. Not only does my arm kill, but every muscle in my entire body feels like its on fire. Even my teeth hurt. Its now 4:30am here in the US and I have yet to get a single minute of sleep. I am just feverishly tossing and turning. Sickest ive felt in years. I truly do wonder if its due to having a more hightened immune response because of fibromyalgia. Still, i do not reget the decision to get the vaccine. If this is anything like what having covid is like, I'll take a day or two of shot side effects over a whole week+ of feeling like this.

2 nd Pfizer vaccine update. No side effects after the 2 nd dose in my case, except some pain at the injection site if I lay on it in bed. Husband had similar reaction as after the first shot, felt hot a day after but no fever. I am very happy to report this and hope it helps. No flare of fibromyalgia symptoms, nothing to report. : )
Each one of us are different but still I hope things will go well for others too.

None don't risk it

The Johnson & Johnson vaccine that is just finishing up clinical trials and will be approved within weeks. It requires only one dose and has minimal sideeffects. It’s effectiveness is the same as the others.
