I take 30 units of levemir before bed time. I have been using levemir for a while now and the past few days when i inject my levemir it burns really bad as if i was just stung by a hundred bees in the same place. Never got that bad of burning before. I also take humalog 5 units before each meal and that one never burns that bad either sometimes it stings a little but nothing much. My insulin is room temp when injecting also. Does anyone else get a horrible burning when you inject? My syringes are 31 gauge x 5/16 needles but i dont think it has anything to do with the needles. Any info advise would be greatful.
