I got the flu shot Wednesday. I have noticed that I now have a painful lump under my arm that wasn't there until I got the shot. Is this a common side effect of the flu shot?

Uncommon not harmful: It's not a common side effect, but it probably indeed is due to inflammation from the immunization. In a way, this is good: it indicates your immune system is responding and you should be well protected from influenza. It should clear up soon, but return to your doctor, or wherever you were vaccinated, if severe, any fever, or if pain continues more than a few days. ...Read more

I have a lump under my arm and feel short of breath and faint. I got the flu shot a week ago but I don't know if its that. Some have said possible leukemia?

I have a lump under my arm and feel short of breath and faint. I got the flu shot a week ago but I don't know if its that. Some have said possible leukemia?

Get evaluated.: Unless the folks who are saying "possible leukemia" have done the proper tests (bone marrow aspiration, cbc), i'd steer you away from accepting their diagnosis. But feeling faint, shortness of breath, and a lump under your arm are all potential warning signals. See your doctor for an evaluation. An exam and some blood tests will provide reassurance - or information you need to know. Lgromkomd. ...Read more

I got a flu shot on Tuesday and within a few hours developed a small lump on the back of my forearm that started very soft and now feels fairly firm?

I got a flu shot on Tuesday and within a few hours developed a small lump on the back of my forearm that started very soft and now feels fairly firm?

Hematoma: It's possible that a small hematoma or bruise may have been caused by the shot IF this swelling is at the site of the injection. If the injection site is not related to that lump, then it must be something else such as a muscle 'knot' or localized spasm. If it's a hematoma I wonder if you are on blood thinners/have a bleeding problem? If so, you should tell your doc. Also if fever develops, call. ...Read more

Had Flu Jab 2 days ago and my front of the shoulder at injection site hurts which is to be expected but my arm pit also hurts. No lumps found any idea?

Had Flu Jab 2 days ago and my front of the shoulder at injection site hurts which is to be expected but my arm pit also hurts. No lumps found any idea?

Sure: The vaccine can cause a generalized immune and inflammatory reaction and it would not be unusual for that to extend around under the shoulder and include the axilla/armpit. As you were advised, you can ice it or take ibuprofen or naproxen for a couple of days. It really should dissipate within the next day or two. Good job on getting your flu shot:) ...Read more

Contracted flu like virus in Dec, all symptoms gone except armpit pain both sides. Doc checked - no lumps after exam but still sore esp morn/evening?

Contracted flu like virus in Dec, all symptoms gone except armpit pain both sides. Doc checked - no lumps after exam but still sore esp morn/evening?

BP management: If you are having pain during the daytime, perhaps it is related to muscular strain. If there are any masses, lymph nodes which can be felt, I would suggest a follow up visit with your PCP. This problem is unlikely to be related to the flu illness which you had in December.
Since you have high BP, then regular check ups are indicated. ...Read more

My arm hurts after flu shot?

My arm hurts after flu shot?

Everyone has that: I think everyone has a soreness around the injection site which may feel worse the day after, but gets better quickly. The vaccine is injected directly into the muscle and irritates it temporarily and mildly. Many places offer an education sheet to keep for reference when vaccines are administered. It explains possible side effects and if there should concern about any of them. ...Read more

Arm itches 2 days after flu shot?

Arm itches 2 days after flu shot?

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. If there is a little redness, that's ok, a lot of redness, or a spreading rash, should probably get you to see your doctor. ...Read more

My arm hurts after the flu shot?

My arm hurts after the flu shot?

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

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

Are redness and swelling and pain normal for the area of a flu shot? I got mine yesterday and I can hardly move my arm.

Redness yes: BUT to the degree of "can hardly move my arm" is not usual for flu shot
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
BUT
local infection can also occur and is serious. Gets worse over time. Heating pad doesn't help. ...Read more
