Mom replying. My son (POTS resolved to OH in 2018) got his Pfizer booster today. Earlier doses caused extreme fatigue and recovery was two weeks. The Pfizer booster caused him a “panic attack” five hours after the jab was given. Classic symptoms that resolved in 40 min. He’s hoping that will be it. The adrenaline rush will cause insomnia probably for a few days. But then, his sleep pattern has been dysregulated —staying i upp but resting most of the night. Bed I think panic attacks should be renamed. The term has too many psychological implications for people with dysautonomia who want to be helped. Is there anyone who’s had a similar experience with the booster? Thanks.
