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. 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
