I am an active 64 woman with no prior health issues .I had the 2 Pfizer shots in 2021 and did not have any side effects. However In December 2021 I had the booster shot and the next morning could not walk on my left foot. I ended up having a superficial blood clot . My doctor recommended Advil and it eventually went away. However now, both of my ankle and feet hurt terribly when I walk. Every night I have pins and needles and numbness in my feet. The feeling is as if my feet “fell asleep”. I can not walk long distances without any pain. I never had this kind of ankle pain and have associated with a reaction to the booster. I am seeing a foot & ankle doctor next week. This is very concerning to me since I love to walk everywhere and now feel constant ankle and foot pain.
