What should you do if your arm starts hurting after a flu shot?

Answer 1

It is quite normal and not uncommon for your arm to sometimes be tender, red and swollen at the point of the injection of the vaccine. This is due to the desired immune system response to the vaccination. It means the shot is working and so is your immune system. It usually lasts less than 3 days. The best thing to do, even though it may hurt more at first, is to use the arm normally. The more you use it doing normal things, the less it will hurt. You can take mild analgesics like Tylenol or ibuprofen if it is too uncomfortable, or ask your pharmacist what would be helpful to make you more comfortable. But the best thing is use and time. If it stays sore for longer than a few days, contact your health care professional to be sure that you don't need an exam to rule out a bacterial infection from the needle. Drink plenty of fluids.

Answer 2

That is longer than the typical muscle aches and local site soreness that can follow IM flu vaccinations. These local site reactions last usually only for a couple of days. You should seek medical advice about your particular symptoms; you may need immediate attention for a bacterial infection or other problem that needs treatment.

Answer 3

just cause your arm is sour from the needle not much more
