If it wasn't ready then chances are the core of it has not come out and you may have irritated it or may have an infection. Try the warm compress several times today and see if you can draw it closer to the surface. If doing the warm compress doesn't help then you should see your doctor for possible antibiotic. If severe enough it may need to be drained, but that would be the worse case scenario. I would do the warm compress and go from there.. Hope that helps.
