Blood clots have been a known side effect of blood transfusions long before the covid jab, particularly RBC transfusions. Thecclots can form several weeks after the transfusion.
You’d think someone would have said something as I had no idea what had happened and waited several days at home thinking it might be a back problem. I’d already spent 23 days on my back in a hospital bed and I had severe nerve pain from my L5/S1 that I recognized as such. I waited from Saturday to Monday. Then I called my GP and had to arrange for a wheelchair to get to his office as I couldn’t take more than one step.
Then, incredibly, my GP realized what the problem was, but instead of sending me to the ER, he waited for an ultrasound scan of the problem that he scheduled three days after my initial visit. I asked him why, if he knew what it was, he didn’t just send me downstairs to the ER and he simply blushed and shrugged.
The hospital staff was amazing. The doctors were simply following protocol whether it made sense or not.
