Hi just wandered if any body had any advise for me that would be helpful. Have phoned 111 but not really much help. I came out of hospital sat 7pm after a shoulder op. Since I've come home my noporapid is basically not working (aswell as before) I know my bodies under stress and inflammation but wanted some advise. Normally my readings are 4-7 99% of time with amount of daily novorapid 10-16 units per day. Yesterday I did 110 unit and can't get below 10 bloods. Today I have already done 32 units and I'm 16.1 bloods still. What action should I take. My surgery opens tomorrow but wandered if any one had any experience from insulin taking no effect or little effect after theri op. Tia
