I had breast surgery to remove a papilloma two weeks ago and had no pain at that time...now all of a sudden have pain. is that normal?

It's possible: Pain and post surgery care has many variables. This is likely within normal. If the pain is not controlled with your pain medications or anti-inflammatory over the counter medications then okay to check in with your doc. There are other possibilities.

See Doctor: Postsurgically, most of the discomfort a patient will experience occurs soon after surgery; given the delayed onset of your pain, best to be seen by your surgeon. Only by doing so can complications ( which can be associated with pain) be ruled out and treated if present. Best wishes.
