I received both doses of the vaccine and I didn’t have any flares up at all.

I got it (Moderna) last week I had a very sore arm, and a flare in progress but it didn't seem to do anything negative. I hear the second dose has more side effects.

I had my second Moderna Vaccine 2 days ago and my reaction was very similar. Since then, I have had pain intensifying in each armpit... along with muscle pain and fatigue. I am experiencing less pain on day 3...
