I have some type of nodule that comes and goes.starts above my left eyebrow and then spreads as far back as my temple..usually stays for a day or two and goes away.when I press on iti get pain and pressure on the opposite side of my head. Now I suddenly have a small nodule above my lip that spreads into the nostril and goes away after a couple hrs only to come back. A few months ago I had a golf ball sized lump under my chin that stayed for several days..whatf could this be?
