Have you tried in the upper thigh? if the canula length is over 30mm you should be ok. Can be a bit tricky pulling trousers down in case you pull it out. Also if the lipohypertrophy is not bad try around the areas, avoiding them. I was told that you can vary the sites on the abdomen either side of the belly button around to the side. I do use the silhouette cannulas but couldn't tolerate the Sure-T. Hope you have better success with the sites.
Take care
