I could see how your docs might be reluctant about you getting boosted, as your symptoms seem a lot like a adverse drug reaction. I'm in the same boat, in that getting booster this time is a difficult decision and my docs are on the fence & reluctant to advise me. I have gotten all the previous vacinations as soon as they were available & we are pro-prevention. My wife & I have not yet had Covid that we know about. We avoid crowded inside spaces & mask when we can't. We live in a very rural area. In Feb, I was hit with a severe case of percarditis and hospitalized for 10 days where they took a liter of bloody fluid from my pericardium. The chest pain was horrible. That also caused AFib to AFlutter which they had to do an ablation to convert my heart back into sinus rhythm. They could not find any cause & also I was on a March-Sept CV19 booster schedule being in the high risk group at 72 with a stent, and TAVR. The pericardtis was "not associated" with the boosters, as it would have happened within 4-5 weeks after boosting. The timing was way off.
I'm fully recovered now without any side effects, but it's been a full year since last boosting. I missed the March booster while hospitized.
Bottom line is getting the booster creates a 3 times greater risk of pericarditis. Getting CV19 without vacination creates a 35 times greater risk of pericarditis and adds risk of a severe case of CV19 or Long Covid.
My 3 docs are saying the CV19 cases they are seeing are milder even amoung the higher risk elderly & unvacinated. They are reluctant to make a call in my case. We travel to the city for serious medical problems, so my docs are university professor level. So, it's totally on me to decide one way or the other about boosting. Odds given above, boosting is still less risky, as I can't count on the "milder strain" theory. So being logical, logic dictates getting the new Fall booster, but I can't say I've decided that......yet!
I know what it feels like to be in your spot!
