I know there is something out there, some of my family in England were sick, similar symptoms as yours. My niece lost her sense of smell, she is very worried that she would not be able to smell things like gas leaks. Sadly it scared my family into getting the shots, all I can do is pray they will be alright, I am doing my best to inform them why they should not get the booster. My Brother had 2 shots of AZ, he went from being very fit for his age, playing squash, badminton and tennis, to hardly able to walk. He had severe pain in his arms and legs, he's on steroids, and feeling better, but he's slowly being weaned of them now, only time will tell if the problems return. God Bless stay safe and strong.
