Has anyone experienced this? I had a flu shot yesterday. Last night, about 9 hours afterwards, the injection site became very sore (which I expected). But soon after and since then, my entire right arm down to the fingers has these flare-ups of pain. Sometimes the pain will originate at the elbow, sometimes at the forearm. Sometimes my upper arm. These areas of my arm will start to hurt, last a few seconds, then it goes away.
The soreness is almost gone from the injection site, but although the other pain abated somewhat this morning, now it's back to the way it was last night. I asked some people at work about it today and only one person said that their whole arm ached after a flu shot. I'm not sure that I'd describe this as an "ache." It is pain. My movement is not restricted.
