Just wow.
I would be so angry if this was the case with me. I was concerned with how quickly they rolled out the shots (I don't refer to these as a vaccine because they are not).
And giving the approval knowing it can induce PMR on us older people? Unforgivable.

Interesting. I was diagnosed with PMR in April 2015. My symptoms started in the fall of 2014 near the end of an allergy shot 'build-up' . . . two shots (one in each arm) twice a week . . . for several months. The onset was over less than a week.

When I brought it to my allergist's attention she said there was no way my allergy shot build-up would have created such intense pain (this was pre-PMR diagnosis). She was a lousy doctor and I didn't have a very high opinion of her in the first place. Fortunately, my primary care physician took me seriously and I ended up in the hands of a great rheumatologist. I just wish there was more that could be done to help with the pain . . . although, I can manage it now.
