I have a white pimple like bump that hurts outside my right eye after blepharoplasty. How do I get rid of it?

Hello. I had belfaro 30 days ago and since it's my second time I am aware of he healing times etc. However where one of the selfdisaolving stichees was (the "knot" under the skin of the stich" this time a pimple that hurts shows up. It's the same as it was after 7 days and when I touch it it hurts. On the left I also have a little bump but that one is healing normally and does not hurt nor does it have a pimple. What should I do? I won't be able to see my surgeon for another six months. Please help
