Hi I've been using levemir since November as I went on a dafne course and they made me change to this from lantus. When I first started it I got huge lumps and black bruises on my butt, but now not many brushes but I still get lumps. I try all different spots on my butt, and have even tried my stomach but that hurts.I don't do my legs as I've been injecting in them for over 30 years and need them to have a rest. Sometimes I don't get a lump but I do more then I don't. I'm Thinking of changing to something else.
