Hi Meep,
I'm on the animas pump as well. What type of sets are you using? Some times when you hit a patch of muscle it can be very painful. I'm always a chicken when it comes to changing my sets as I was with injections and doing finger pricks it always takes me ages to press the button and slide a set in. I would suggest maybe asking to try some different types of sets just call animas or get your parents to and get a selection of different types of sets. Some times as well you just need to try a different area of your body to put them in anywhere where there are any giggly bits is a good bet that includes the top of your arms, legs are an excellent place, hips, lower back, bum. The more you rotate your pump sites around the better. Sometimes if you are keeping your sets in the same area a layer of muscle (very small and thin) can form when it's not supposed to be there. This can make putting sets in hurt as well, not to scare you, after a time of not putting insulin in that area it breaks down back into fatty tissue. When I came off injections my legs, where I mainly injected, where very swollen in big lumps after 7 years of injecting after 6 months they were back to normal. I found that I didn't like the automated set firing thingy and prefer to use just manually putting my sets in. With that I can chose the angle and I usually manage to skip the sore muscle bit. I can also change my angle midway if I go too close to sore bits (as I put it in really slowly) and because I'm such a big chicken I don't like pressing the button to fire a set in I would be sitting around until I feel ill with a high before I could press it.
On a differnt note I found that whenever I had cognetive behaviour therapy I learned to put positive thoughts around when I injected or tested my blood sugar and there are things that I still use today that I find really help reduce the stress and anxeity around dealing with my diabetes. Being in a calm relaxed atmosphere when doing things not feeling in a rush, putting on my favourite music and giving yourself a reward after doing anything you don't like. When you change your thoughts around your diabetes sometimes it's easier to deal with the pains and stresses of it.
I'm sure you'll get lots of other replies with tips to make it less sore. Good Luck Laura
