H, crystal i went to the emergency room today and they told me exactly what you said. It needs to be surgically removed! but i wandering why they couldn't do it with all the skilled professionals they have in the e.r..
You said 'golf ball'. That is huge, and a simple lancing may not be enough, as boils of this size often just come back. The next option is to have it SURGICALLY removed, where the entire contents of the boil PLUS the 'sack' that holds it is removed, and the hole is stitched closed.
