Why Does My Arm Hurt After Getting A Flu Shot
Also known as influenza vaccines, flu shots are given out once a year to protect against the flu. The flu shot stimulates the immune system to build antibodies to three or four strains of flu viruses in the hopes that it will offer protection from the current strains present in the community. Each year the Centers for Disease Control (CDC) monitors the strains of Influenza globally and incorporates the appropriate antigens in the new vaccine. For best protection the vaccine ...Read more
GOOD!!!!: That is a good thing! That means the shot is working! In fact, many shots have something called an adjuvant in them. An adjuvants job is only to dram more immune response to the site of the shot. Immune response = swelling, redness, pain and itching. The flu shot is the same. So, congrats, your shot worked! cellulitis after shots is rare, but if red extends past a joint or you have pus get checked. ...Read more
Everyone has that: I think everyone has a soreness around the injection site which may feel worse the day after, but gets better quickly.

Can left arm muscle pain be sign of heart attack? Woke up feeling like when you get arm soreness from flu shot, but been two weeks since flu shot
After getting a flu shot, the injection site swelled & was hot. It itched mildly. Now, 2 days after shot, I have a rash under my arms. Is this related?
May be: The interval between your flu vaccine and the rash may suggest that the rash is due to the vaccine. However, it may be a coincidence. If it does not bother you, I would wait. If it itches, would take an antihistamine such as cetirizine, Loratadine or fexofenadine (all available otc). If no better if a few days, see your physician. ...Read more

That's OK: Every vaccine is intended to get your immune system's undivided attention. When it does, you get a little inflammation at the site (a sign the vaccine is doing its job), and sometimes that inflammation can precicipitate an itch.

Got the standard flu shot today and had some slight raised redness. What is really weird is that I also have the same reaction in the opposite arm??
Vaccine reaction: It's normal to have mild local reactions on the same arm where you receive flu vaccine. If there are red spots elsewhere on your body, it is possible that you are having an allergic reaction to your vaccine, and I would contact your doctor, and you can try a dose of Benadryl (diphenhydramine) to see if that helps the rash. If you are short of break or have throat swelling you should go to the closest ER. ...Read more
I'm a new nurse I gave an IM flu shot today and the patient complained of tingling and slight numbness down the same arm What do you thmean nk happened?
You probably came: Close to/contacted a little nerve with your needle. There is really no way to avoid this. Injecting the needle firmly and quickly may allow nerves/tiny vessels in peril to slide away from the needle rather than being pierced by it. It is a temporary phenomenon and will not result in permanent harm. Don't let it discourage you as your begin your helping career of "jabs." ...Read more

without an exam, I can only give general information, and local soreness is the number one side effect of the shots. Generally lasts under a day. Heating pad resolves
local infection can also occur and is serious. Gets worse over time. Heating pad doesn't help. ...Read more
