I had one on my shoulder for years, and finally got it drained. It exploded all over the doctor and the wall of her office. :eek: I'd waited so long that it was still emptying for more than a week. It hadn't been dangerous at all, but it was right under my bra strap DRIVING ME NUTS, and I was glad to have it gone! I wished I'd gotten rid of it sooner, because it took so long to finally empty out that I couldn't swim in fresh for a month because it had to be kept open to drain.
Love, Columbine
