I have a cyst on the back of my head which has been getting bigger for years. It started hurting on Friday and DH looked at it yesterday and poked it and 10 years' worth of gunk came out (I think he rather enjoyed it!) and it was all flat.
However, today, it seems to have refilled a bit. He's had another prod and has got a load more icky stuff out and it's flat again but will it just keep filling up?? It feels painful today :(
