Cannula allergy: heard of once, year(s?) ago, Friends for Life, Exhibit Hall of Vendors, steel infusion sets salesperson promoting cannula allergy concept. Pretty sure German-made steel sets? Barely attentive because at least we don’t have some kind weird of allergy to plastic. But now—maybe allergic.
Sites used to work 72 hours. Then 48 hours. Now…36 – 40 hours max, then high/doesn’t really come down—>correct w. syringe & change site, then normal-normal-normal 36 hours. Finally catching on. Old site little bit pink, mosquito bite-looking, nothing horrible/no oozy yuck. But could be cannula allergy puff-up choke off insulin?
Another clue: more complaining about feeling the site. Not pain but aware. Itchy? No. Hurts? No. Just can feel it.
