ok so I've been a diabetic a long time and this has happened before.....I sometimes react to my basal insulin...but I change my needles each time.......I thought I 'd see what others say. this morning I have injected in each leg for my basal and bolus.....the bolus made an instant lump and now a bruise and is very sore.....I'm on 5mm needles and I'm over weight....any thoughts
