I just received a vaccination today at around 9:00 in the morning, and it is still hurting really bad now at 8:40 in the evening. Is this normal?
Since it's unclear from the question what vaccination this was, I looked up two likely cases: the flu vaccine, and the DTaP booster, because these are vaccines regularly given to adults.
The flu vaccine can cause soreness, redness, and swelling at the spot where the vaccination was given. If the pain is more than mild, or lasts longer than a day, ask your doctor.
DTaP, or Tdap
Pain at the injection site occurs in 2 out of 3 adult patients. Severe pain is rare, and should be discussed with a doctor.
A rather comprehensive overview of vaccine side effects can be found at the CDC website. Soreness and mild pain is a side effect of many, but anything severe or lasting more than 1 to 2 days should be discussed with a doctor.
