I've had 3 Pfizer jabs-- two back in the winter and one recent booster. I did not have anything happen afterwards which I would call a reaction, except a sore arm. I asked the nurse at Walgreen's who gave me the booster if the shot had thimerosal in it, which is a preservative I don't like because it has a mercury compound in it. Scientists do claim thimerosal is safe.
"No," she said. Pfizer vaccine is preserved by extreme freezing temperature. I didn't feel anything bothersome that night or the next day. I'm 76 approaching 77 and in fairly good health except for adult onset asthma. I was born with scoliosis and the lower part of my spine permanently fused to my pelvis----transitional last lumbar vertebra, and lordosis. So my back has given me trouble, including extreme stiffness in my lumbar spine, pain, and plenty of chronic pain in my thoracic spine.
Skybuck, you should get a scan to see if you have not been abducted and implanted with an organic or other microchip like this doctor (who is now passed on) used to find in his patients. His name was Dr. Roger Leirs. Please investigate. You sound like you may have one of those implants, you are so weirded out. Good Luck!
