I had to get to the ER with a dangerously low platelet count...I'm better but I have to see the hemotologist this week....it was very scary! They said my brain or my heart could have spontaneously started bleeding [I had to get a CT scan]. Kinda covid-related...I already have an autoimmune disease, so the vaccine activated my antibodies to attack my platelets...suppose to have 150,000 to 250,000...I had 4000! With the IVIG therapy and heavy IV steroids, it went from 4,000 to 6,000 to 11,000 to 107,000! Still on oral meds now so I go back and they'll see if they need to adjust it.
