I'm on a kind of medication that are described as chemo drugs. They are not actually - they are tumour inhibitors and they have a side effect of a 'facial rash'. It's not a rash at all but a regular bout of perfect yellow pustules mainly on and under my chin that pop in a very satisfying manner. I had eight this morning. Once dispatched they leave no mark. I spring out of bed in the morning to look at my morning gifts!
