Haven't had one of these things since the 80's. Had the shot 10/3 - and of course, as I expected, arm ached for for a few days or a week after.
However it has never stopped aching - no direct point of pain just an overall ache ---- well this morning I have this painful bump towards the inside of my arm, directly across from the shot site.
Calling the doc as soon as they open this morning.
Anyone else have a bad reaction to this?
