Thank you everyone for your welcome. I've been type 1 for 52 years, on a pump for 10 years. As someone else has already mentioned, I'm also having problems with Accu-check flexlink cannulas despite using them for most of the time I've been on a pump. 2 different lot numbers have unusually been very sore when inserted. Rang them today and they are going to replace, also handset as it isn't always showing a correction dose when bg is high.
