Hi All .
Were your 'lumps' pink or red in colour ?
Warm to touch and swelled up later ?
If they were - it may be possible they were 'lipos' inflammation of injection site
Please check this with your own GP/DSN though if you suspect this .
I had this with levemir/lanctus we eventually worked out I was allergic to the preservatives
in the human insulin.
Hence my swap over to hypurin porcine animal insulin .
Never had this since the change over of insulin with myself.
Mine were painful both inside and outside of the skin .
Red in colour and hot to touch , raised circular welts spreading over injection site areas .
Even bending over or rubbing on clothes was painful .
[I use the 5mm needles]
Hope this can help.
Anna.
