    Skin Reaction to Flu Shot?
    An_187562 posted:
    I received a flu shot last week and the day after I developed a skin rash about an inch away from the injection site. It's a raised bump, very red, itchy, has tiny little bumps on top of the large red area. Is this a reaction to the shot or something else entirely? I have been putting hydrocortisone cream on it but it's not going away.
    Rod Moser, PA, PhD responded:
    I don't know....I have no way of examining your injection site. Any vaccine can cause a local reaction, but without the ability to see it first-hand, I really can't offer you a defintive answer. We occasionally see infections as a result of an injection. The "something else" could also be an insect - mosquito bite?

    If this possible reaction is concerning you, you may need to see your medical provider so you can have this properly examined.
    MissJulie1977 replied to Rod Moser, PA, PhD's response:
    Thanks, I figured that would be the case since you can't see it. Spider bite crossed my mind so I guess I will read about that next. Thanks.
    UncleHank responded:
    I have a reaction to a recent shot that covered 3 types of flu. I have had it for 2 months now and i thought "spider bite" also. It is oozing and open. I am not too concerned about it but would like to know if you found out anything yet? Thanks
    Rod Moser, PA, PhD replied to UncleHank's response:
    If you have an area that is "oozing and open", this is a cause for concern. Any injection...not just a flu shot....can cause an abscess (from germs from the skin surface going deeper in your tissue).

    I think you need to see your medical provider so you can have this oozing, open area properly examined.
