My original post was related to this topic. I got J&J and two weeks later symptoms started and became at unbearable. Diagnosed with PMR at 4 weeks and started 10mg prednisone - better in 3 days. Now on 5mg. Friends and family were/are sceptible of getting a Covid shot after seeing me - a healthy, active 74 year old decline so rapidly. Still think there is a connection. Next follow up in October.
