Got a flu shot and now my arm is sore. Is this an allergy?

No. Soreness around the injection site would be a "normal" expected reaction. Ibuprofen, 1-2 doses, 6-8 hours apart should relieve the pain.

Tylenol, (acetaminophen) ice. Take an over-the-counter pain reliever like tylenol (acetaminophen) and right before going to bed apply ice wrapped in a towel on your arm (a bag of frozen peas works well) for about 10 minutes. The pain shouldn't last more than a day or two.

Got a flu shot yesterday and my arm is hot and my muscle is sore and weak. Is this normal?

Not for most. When you have what you describe it is usually because you have a sensitivity to something in the vaccine. I would check if the form of the vaccine you took had Latex and or preservative in it. Allergy to eggs could cause this. If just mild inflammation and sore muscle is not unusual. If not allergic to Aleve (naproxen) or the like take this plus cold compresses at the site. Infection is unlikely but possible.

How long is a person's arm sore after a flu shot?

Why does my arm hurt after I get a flu shot? It feels sore.

Inflammation. Your arm hurts because the injection itself or the flu vaccine injected has produced a low grade inflammatory response and this causes pain. It will pass uneventfully. If it continues or worsens go back and see a doctor.
Expected. Often people will experience soreness in the arm that received the flu shot as the body responds to the foreign material and this is normal as long as it doesn't last for more than a week.
