question: I have had a fatty lump on my bra line under my arm for three or four years. It has very slowly grown in size to approx 1.5 inches in diameter. It has never been painful until now. It has grown much faster in last couple on months and for the last week has had a lot of redness, burning sensation and pain and swelling. I have appointment with specialist in two weeks time. Do you think this sounds infected and should I see a GP now or wait?
