Infected Cyst

I’ve had a cyst at the base of my neck for two or three years and it hasn’t caused any trouble, until this Monday. Now it has swollen up so that there is a lump extending from the top of my shoulder to my spine (about 9cm across). This morning it had turned from red to purple and so I’ve been to the medical practice and seen the practice nurse who’s prescribed a week’s worth of antibiotics (flucloxacillin) and I’ll be on a list to have one of the GPs remove it once it has calmed down.
