United Kingdom

On the evening after, I felt chilly and a bit wabbit, though I wasn't running a fever. That passed in a few hours after I put on an extra fleecy jacket, and I was fine the next morning.

The muscle where I got the injection is still a bit tender and sore on being pressed - comparable to lactic acid pain after over-exertion (I did do some moderately heavy garden work in the afternoon after my injection, but my other shoulder doesn't have the same problem).

Other than that, no issues to date.
