Honestly at this point it should be examined clinically by a doctor and you should have basic tests done like a CBC which will tell whether there is active infection going on or not.
I say this because sometimes the abscess (puss formation) is deep seated and there is no discharge from the puncture site.
Anyhow, if there is no infection, this should have settled down or at least started to improve by now.
Instead of Tylenol, you should take Motrin or Aleve (which are not only pain medications but also anti-inflammatory drugs) which will reduce the swelling as well.
Application of cold packs will also help.
And watchfully monitor this over next few days, because if this does not improve, persist, or gets worse, see your doctor for further evaluation (i would have examined this today, right now).
It was a pleasure assisting you and thank you very much for visiting us.
