The VAERS (vax adverse reaction) site is here: https://vaers.hhs.gov/ It's pretty easy to use. I reported an adverse reaction to the first Shingrix shot.
Doctors are usually dismissive of correlations, but they often chart it so that if they hear it enough they report or investigate. But clinicians don't like diverting from their protocols--or the hospital systems they work for don't let them. Opens them up to lawsuits if they diverge from prescribed standard of care.
For example, I asked a dermatologist if worsening rosacea could be ET-related. He said no, gets worse with age, you're old, ergo ... Then he said I was the second patient with ET who asked him that, asked me more about ET, and wrote it down in my chart. So I planted a seed, even though his standard rosacea regime has helped a lot.
I will say that platelets can take big jumps once the proliferation starts. Dad experienced this.
Interested in what your doc saw that indicated "sticky blood."
Thank you for letting me know about the website to report adverse reactions to vaccines! I definitely will report adverse effects I had immediately following the Covid vaccination that lasted for a month, and then the start of my platelets rising.
