For the past 1.5 weeks, my husband has also been dealing with a large abscess on the back of his neck. It started as a small, red lump, but then it grew and became so painful it woke him up at night. It had to be lanced, and then the abscess had to be packed (a small strip of cloth is put into the abscess to help it drain) every day. It's finally closed up now, and he is finishing his course of antibiotics.
Antibiotics are such a wonderful thing. If only we had good antivirals. I hope I live to see humanity triumph over colds and influenza.
