I am on a animas pump, and normally use my stomach and sides to put the insets in. Recently I noticed a site that I had used, had left a small red lump which did not disappear like it normally does. It has now grown in size, and although not painful, looks like it could be infected. I am always very careful with hygiene, and am not sure what it could be. It looks like scar tissue, and I am planning on visiting my doctor next week. Would anyone be able to give me some advice, as I am concerned. Many thanks.....
