Might be a silly question - but have you checked your insulin is ok and still in expiry and has been stored in a fridge below 8 degrees, I would chuck this insulin out anyway just in case it's this and it does sound like your insulin isnt doing it's job properly - otherwise change your injection site, you may have hit a lumpy area ? I try and rotate sites as much as possible, so background now goes in my bum which is nice and fatty and short acting goes in and around my tummy, but rotated all the while.
Hope it's coming right again, hate the highs and lows !!
:crazy:
