I had facial filler without any problems but had a flu shot. Did the shot cause these bumps?

Thank you for sharing your excellent question. Unfortunately without an in-person examination, or full series of photographs, it is difficult to offer definite advice. I would see your injector for an evaluation to make sure your filler is intact and that the lumps will resolve spontaneously with time, or Benadryl.  Hope this helps.

I am a family physician that offers fillers in my office as well as flu shots.   I am fairly positive that the flu shot did not cause any bumps only where the fillers were injected.    If it was the flu shot, you should have red bumps pretty much all over your body, if it was an allergic reaction.
