I have had a lump on my head for a couple of years, it formed on my head after a stone wear loaf pan fell out of a cabinet and hit my head, recently I noticed it was a little bigger, it is soft but almost feels like it s filled with fluid or it feels similar to a lipoma, today I as poetically poked it with a needle and it started leaking clear non odorous fluid, it shrunk a bit, as I palpated the area I can feel a hold in my skull which the bump has covered up, it s a hole the size of a fingertip. Is it possible it was CSF leaking and I have a serious problem?
