Symptoms: Fever Headache Joint Pain
Hollywood, FL, USA

“1st shot went relatively well. Had only minor tightness of throat for few minutes, felt light headed, and then felt feverish for a few days. Had join pain for a few days, but it got better later. Felt much better overall in a few days, better than before the shot. The second shot went well also, no... See Moretightness in the throat, no light headed, only soreness of arm for about two days. However, after one week, getting headaches/ mild migranes that don't go away and I don't really suffer from these. Had no major changes in routine or sleep habit to attribute to it. Headaches got worse after one week being vaccinated. Also, had a few episodes of weird symptoms I had never felt before- like if the heart skipped a beat... If it will continue, I will address this with my doctor. At this point, sharing, so that if anyone else has similar symptoms, we can bring it to the attention it needs. Overall, feel better than before getting the shot. I suspect I might have had long haul symptoms from possible Covid in March 2020- no tests were available to me to confirm the positivity then, but had many weird illnesses that are better now. The irregular heart beat/shortness of breath on occasion (only one to two seconds) concerns me a little. At this point, still happy I got the shot as I'm in the high risk category from complications and could not risk not getting vaccinated. See Less
