DKA again?

Hiya, i only ever seem to write on this thing when i'm having a dilema and never seem to return the favours by helping others; so i apologise.
anyway heres my newest situation.
I've been feeling rotten for a few days now with 'flu like' symptoms even though i was a good girl and had my jab about a month ago. i've been testing my bloods which considering the lemsip i am drinking (tablets where too difficult to swallow due to my swollen glands) have been fairly even maybe a little high but nothing i'm not used to (around 9). I've also been checking for ketones as this time last year i was admitted to the high dependancy unit for DKA, the levels have been up and down abit and at the moment they are moderatly high but havent wee'd for quite a few hours (Could this alter the concentration?) i also vomited earlier this afternoon and still have a few stomach pains.
any ideas what i should do?
i still live at home but my parents are on their way to visit my auntie in blackpool and i live in the north east so i dont want to worry them with such concerns.

any thoughts would be great,
Shell

ps. i hate hospital.

Panic over, my ketones have gone back down no negative which is good. Thanks for your opinion jopar . i phoned the NHS direct line and they told me if i have any more concerns just ring my emergency doc. I think my body must just go into a bit of a frenzy whenever i have an infection. but you are so right, hospitals are horrible but they are there to make you better in the long run.
once again thanks
Shell
