twas a large 5-6cm cyst that has lived peacefully on my upper back for many years. Actually it was removed some years ago but grew back. Anyway, became infected, and I finished the antibiotics the GP gave me today. He said if the infection doesn’t settle I should go to A&E to have it ‘opened’. Do I go tomorrow if it isn’t better? Or hold on in case it resolves. There has been some small drops of gunk out that hole but not a lot. And no i wont’t squeeze it - it’s excruciatingly painful!
