saw this site and joined because i need some help for my hubby.on friday we were away with the caravan and his pen ran out,took a phial out of the box and used that,but we think this was at least 2 months old and had not been in the fridge.his levels started to climb and when you consider he always runs at between 5 and 6 when it hit 17.5 he was feeling rubbish.went to the local a=e where they gave him some new insulin but they said that 17.5 is nothing to worry about,since then his levels have been running at about 10 which is worrying him,he's been diabetic for ten years and never had any problems before and he just wants to get things back to normal(for him)has anyone used old insulin(mixtard 30) before and had any problems like this,are there other reasons his levels could have gone up,and will things settle down again.he asked the diabetic nurse and she said everythings okay his levels are not what they class as high but what he cant get through to them is that its high for him and it worries him.
